Constants

Integer Constants

Numbers are a fundamental element of every programming language. They can be used for calculations using binary operations, and can provide you with a tool to compare anything with boolean (0 for false, 1 for true) representation.
All concepts, such as bytes, strings, objects, etc., are ultimately just numbers.

The Deen compiler allows you to create number constants.
Currently supported ways to write numbers are: decimal, hexadecimal, and binary.

// 3 ways to write "1000"

1000 // -- decimal
1_000 // -- decimal with separation
0b111110100 // -- binary
0x3E8 // -- hexadecimal

You can do any math operations with the provided constants:

0b1101 + 0xF * 2;

Float Constants

Float constants are a highly useful element for mathematical calculations in programming. They allow you to maintain maximum accuracy in calculations.
To define a float constant, simply use decimal notation with a dot:

1.00 // default number
51.32 // bigger number
3.1415926535897932384626 // PI number

Boolean Constants

Boolean constants are just 1-bit numbers which represents comparison result (0 - false, 1 - true)
To define boolean constant use compiler keywords:

true, false

Char Constants

A char is essentially an unsigned 8-bit integer that contains an ASCII symbol. To define a character constant, simply use single quotes:

'a', 'b', 'c'

Strings Constants

Strings in the Deen compiler are similar to those in the C programming language.
The core mechanics are as follows: every symbol is a char, and a string is simply a pointer to a char array.

To define a string constant, just use double quotes:

"Something here"
"Hello World!"
"Do you reading this?"

Array Constants

Array is a basic collection of ordered data in memory.
To define array constant use brackets:

[1, 2, 3, 15, 144]

Tuple Constants

Tuple is the data structure that combines multiple types by its index.
To define tuple constant use parentheses:

(10, "hello", 'a') // (i32, *char, char)
