The context specifies the maximum precision of the result of calculations and the rounding algorithm if the result has a higher precision than the specified maximum.

It also holds the list of set of trap enablers and the currently set flags. The context is stored in the process dictionary, this means that you don't have to pass the context around explicitly and the flags will be updated automatically.

The context is accessed with Decimal. It can also be temporarily set with Decimal. The rounding algorithm specifies how the result of an operation shall be rounded when it get be represented with the current precision:.

Instead use comparison functions. When an exceptional condition is signalled its flag is set in the context and if if the trap enabler is set Decimal.

Can you see the relationship between the log to base 10 of a number and the number of digits? You will also want to use the floor function. Apparently you can use libraries from Erlang - search for "elixir math library". I know nothing about Elixir. Oh, and instead of floor it appears that you can use trunc to be more succinct.

Meet Elixir, a modern, functional, concurrent language built on the rock-solid Erlang VM. Maybe the time is right for the Next Big Thing. Elixir in Action is a tutorial book that aims to bring developers new to Elixir and Erlang to the point where they can develop complex systems on their own. No knowledge about Elixir, Erlang, or functional programming is required, but it is assumed that a reader has a few years of production experience using mainstream OO languages, for example CJava, Python, or Ruby.

The book starts with a basic introduction to the Elixir language and functional programming idioms. The central part of the book deals with Erlang VM and OTP, discussing topics such as concurrent programming, fault-tolerance, and distributed systems. The theory is demonstrated through a simplistic example that is gradually expanded throughout the book into a fully standalone releasable system.

Adoption is more than programming. You need the case studies and strategies in this book. Learn the best practices for the whole life of your application, from design and team-building, to managing stakeholders, to deployment and monitoring.

Go beyond the syntax and the tools to learn the techniques you need to develop your Elixir application from concept to production. This language combines the robust functional programming of Erlang with a syntax similar to Ruby, and includes powerful features for metaprogramming. This book shows you how to write simple Elixir programs by teaching one skill at a time.

You begin with a quick overview of the Elixir language syntax, along with just enough functional programming to use it effectively. Come rediscover the joy of programming with Elixir and remember how it feels like to be a beginner again. This book is a set of recipes grouped by topic that acts as a reference to get ideas from or to quickly search for a solution to a problem.

You will begin by launching an IEx session and using it to test some ideas. Next, you will perform various operations like loading and compiling modules, inspecting your system, generating a supervised app, and so on. Furthermore, you will be introduced to immutability, working with data structures, performing pattern matching, and using stream modules to generate infinite data sequences.

You will learn about everything from joining strings to determining the word frequency in text. With respect to modules and functions, you will also discover how to load code from other modules and use guards and pattern matching in functions. The lessons are currently available in over 10 languages to help make programming Elixir more accessible to non-English speakers. Joy of Elixir is a gentle introduction to programming, aimed at people who already know some things about computers, but who have little-to-no programming experience.

This book will teach you the core concepts of the Elixir programming language in a fun and enjoyable way. No previous functional programming experience required! This book walks you through the right concepts at the right pace, as you explore immutable values and explicit data transformation, functions, modules, recursive functions, pattern matching, high-order functions, polymorphism, and failure handling, all while avoiding side effects. To get the most out of functional languages, you need to think functionally.

This book will get you there. The Toy Robot is a common interview exercise for new programmers. This short book will take you through how to implement it in Elixir in a BDD-style, with some great explanations and imagery along the way.The difference between our coating "flavors" lies in the tone and feel. They are bright and lively, and the coating is so thin that you can barely tell it's there.

We offer taper wound bass strings for 4- 5- and 6-string sets — check out the bass product section to find out the details. Typically it's time to change when the plain steel strings high E and B show signs of excessive wear.

String life differs from player to player. The answer is simple. Strings go dead for two reasons: corrosion attacks the metal surface, and stuff on your fingers clogs the space between the string windings.

The result: players tell us their tone lasts longer than any other string, uncoated or coated. Sure, other companies make coated strings. But they coat only the surface of the windings, leaving the space between the windings exposed to dirt and debris.

Although it is good practice to wipe off your strings with a dry cloth after playing to remove any loose debris or moisture, we do not recommend the use of any cleaners or lubricants. As you know, sets are made up of wound and plain steel strings.

Unfortunately we do not manufacture custom sets, but you can put one together by purchasing the individual string gauges you need. All retailers can order our single strings. Both string types are popular and therefore selecting the right strings is a matter of personal preference. Here's what we can tell you:. Our innovative Anti-Rust Plated Plain Steel Strings also resist tone-deadening corrosion, ensuring longer life for the entire set.

Phosphor Bronze acoustic guitar strings offer a tone with both warmth and sparkle.We have already learned that Elixir provides double-quoted strings and single-quoted char lists.

However, this only covers the surface of structures that have textual representation in the language. Atoms, for example, are mostly created via the :atom representation.

Computer science has become such a wide field that it is impossible for a language to tackle all aspects of it as part of its core. Instead, Elixir aims to make itself extensible so developers, companies, and communities can extend the language to their relevant domains.

In this chapter, we are going to explore sigils, which are one of the mechanisms provided by the language for working with textual representations.

Parsing Numbers in Elixir

Regexes also support modifiers. For example, the i modifier makes a regular expression case insensitive:. Check out the Regex module for more information on other modifiers and the supported operations with regular expressions.

However, sigils support 8 different delimiters:. The reason behind supporting different delimiters is to provide a way to write literals without escaped delimiters. Similarly, if the regular expression has forward slashes and capturing groups that useyou may then choose double quotes instead of parentheses.

Elixir supports some sigil variants to deal with escaping characters and interpolation. In particular, uppercase letters sigils do not perform interpolation nor escaping. Nevertheless, it is better style to change delimiters as seen above than to escape them. The most common use case for heredoc sigils is when writing documentation.

For example, writing escape characters in the documentation would soon become error prone because of the need to double-escape some characters:. Why is it called naive?

Because it does not contain timezone information. Therefore, the given datetime may not exist at all or it may exist twice in certain timezones - for example, when we move the clock back and forward for daylight saving time. As hinted at the beginning of this chapter, sigils in Elixir are extensible. Sigils can also be used to do compile-time work with the help of macros. For example, regular expressions in Elixir are compiled into an efficient representation during compilation of the source code, therefore skipping this step at runtime.

Although strings are one of the most common data types in computer languages, they are subtly complex and are often misunderstood.

To understand strings in Elixir, we have to educate ourselves about Unicode and character encodings, specifically the UTF-8 encoding. In order to facilitate meaningful communication between computers across multiple languages, a standard is required so that the ones and zeros on one machine mean the same thing when they are transmitted to another.

The Unicode Standard acts as an official registry of virtually all the characters we know: this includes characters from classical and historical texts, emoji, and formatting and control characters as well. Unicode organizes all of the characters in its repertoire into code charts, and each character is given a unique numerical index. This numerical index is known as a Code Point.

In Elixir you can use a? Note that most Unicode code charts will refer to a code point by its hexadecimal representation, e.

The hex representation will also help you look up information about a code point, e. Now that we understand what the Unicode standard is and what code points are, we can finally talk about encodings. Whereas the code point is what we store, an encoding deals with how we store it: encoding is an implementation.

In other words, we need a mechanism to convert the code point numbers into bytes so they can be stored in memory, written to disk, etc. Elixir uses UTF-8 to encode its strings, which means that code points are encoded as a series of 8-bit bytes. UTF-8 is a variable width character encoding that uses one to four bytes to store each code point; it is capable of encoding all valid Unicode code points.

Because UTF-8 is a variable width encoding, the number of characters i. Consider the following:. Some of the genius of UTF-8 is how it reserves certain bits to declare how many bytes are needed to represent a code point. Note: if you are running on Windows, there is a chance your terminal does not use UTF-8 by default. You can change the encoding of your current session by running chcp before entering iex iex. We are getting a little bit ahead of ourselves.

Although we have covered code points and UTF-8 encoding, we still need to go a bit deeper into how exactly we store the encoded bytes, and this is where we introduce the bitstring.
