Constants

Thagore supports immutable top-level constants with explicit type annotations.

Declaring a constant

const LIMIT: i32 = 10

Constants are lowered at compile time and behave like immutable module-level bindings.

Builtin shipped constants

The current repository ships these constants in std.math:

Name	Type	Value
PI	f64	3.141592653589793
E	f64	2.718281828459045
INF	f64	1.0 / 0.0
MAX_I32	i32	2147483647
MIN_I32	i32	-2147483648

Using constants

import std.math as math

func main() -> i32:
  if (math.PI > 3.14 and math.PI < 3.15):
    return 0
  return 1

import std.math as math

func main() -> i32:
  if (math.E > 2.71):
    return 0
  return 1

import std.math as math

func main() -> i32:
  if (math.MAX_I32 == 2147483647):
    return 0
  return 1
