Variables

{{Needs Examples}}
Variables are how FiM++ manages data in memory. There are three primitive data types, as well as arrays and custom objects.

'''Variables''' are FiM++'s way of interacting with data in memory.

== Types ==
There are three basic types of variables:

* '''Boolean values''' represent exactly one of two possible values, such as "true/false", "yes/no", "on/off", "1/0", et cetera. They are stored in memory as a single bit.
* '''numbers''' represent 64 bits of data, in IEEE 754 standard double-precision floating-point format. More information on this format can be found [[wikipedia:Double-precision floating-point format|on Wikipedia]]
* '''characters''' represent UTF-8 data. Depending on the individual character, this can take up between 8 and 32 bits, inclusive. More information on this format can be found [[wikipedia:UTF-8|on Wikipedia]]

== Declaration ==
* {{codeblock|{{code|keyword|Did you know that}}{{tag|whitespace}}{{tag|variable|name}}{{tag|punctuation}}}}
* {{codeblock|{{code|keyword|Did you know that}}{{tag|whitespace}}{{tag|variable|name}}{{tag|whitespace}}{{tag|keyword|assign}}{{tag|whitespace}}{{tag|value}}{{tag|punctuation}}}}

== Data Types ==
The following are all the primitive data types in FiM++:
* Numbers
** Numbers are 64-bit (double-precision) floating point data types
* Characters
** Characters are UTF-8 (up to 8 integer bytes) characters
* Boolean values
** Boolean values are 1-bit binary values

An array can be made of any variable using special keywords (usually, appending "s" or "es" onto a preexisting variable type keyword)

== Names ==
Each variable name has the following restrictions:
* Must not contain any [[reserved phrases]]
** However, literals are okay. Don't forget that this language is case-sensitive, so "{{code|variable|Twilight's {{codeerror|number}}}}" is bad, but "{{code|variable|Twilight's Number}}" is good.
* Must not contain any [[punctuation]]
* Must begin with one non-[[whitespace]], non-[[literal]] character
* Must end with one non-whitespace character

Each variable name also has the following freedoms:
* There is no hard limit on the length
* May have any whitespace character in them (yes, even new lines)
* May contain literals, as long as they are not at the beginning of the name
** for instance, {{code|variable|cloud 9}} is okay, but not {{code|variable|{{codeerror|2}} princesses}}
* May contain apostrophes
* Encoded in UTF-8
