Constants (numojo.routines.constants)

This module defines physical and mathematical constants for use in numerical computations. The constants are defined as class attributes of the Constants class, which is designed to be immutable and efficient for compile-time evaluation.

Structs

Constants

struct Constants

Memory convention: memory_only
Implements: AnyType, Copyable, ImplicitlyDestructible, Movable

Define constants.

Use comptime for compile time evaluation of indefinite precision. 

import numojo as nm
fn main():
    var pi: Float64 = nm.pi
    print("Float64:", pi*pi*pi*pi*pi*pi)
    print("Literal:", nm.pi*nm.pi*nm.pi*nm.pi*nm.pi*nm.pi)

Float64: 961.38919357530415
Literal: 961.38919357530449
