Constants

Named constants are declared similar to variables however, instead of = to defined its value, : is used.

There are few different categories of constants:

• Values
• Types
• Procedures

Value constants

Named value constants can be a character, string, boolean, or numerical value.

#import "fmt.odin";

TAU :: 6.28;
main :: proc() {
    WORLD :: "世界";
    fmt.println("Hello", WORLD);
    fmt.println("The one true circle constant is", TAU);

    CHARACTER_C :: 'c';
}

Type constants

A named type declaration creates a distinct type from its base.

My_Int :: int;
m: My_Int = 123;
// i: int = m; // Error!
j: int = cast(int)m;

Procedure constants
