Standard library

nox.mathx

The same mathematical functions as nox.math, implemented without any C library. They are ordinary Nox functions, so they are always called qualified, and the module works in every profile — including freestanding builds where no libc exists.

import nox.mathx

Capability: none.

Functions#

Function	Description
`sqrt(x)`	square root
`pow(x, y)`	`x` raised to `y`
`floor(x)`, `ceil(x)`	round down / up (result is a `float`)
`sin(x)`, `cos(x)`, `tan(x)`	trigonometry, radians
`atan2(y, x)`	the angle of the point `(x, y)`
`exp(x)`	e to the power `x`
`log(x)`, `ln(x)`	natural logarithm (`ln` is an alias)
`pi()`, `e()`	the constants π and e
`min(a, b)`, `max(a, b)`, `abs(x)`	`float` helpers

Nox

import nox.mathx

print(nox.mathx.sqrt(16.0), nox.mathx.pow(2.0, 10.0), nox.mathx.floor(2.7), nox.mathx.ceil(2.1))
print(nox.mathx.sin(0.0), nox.mathx.cos(0.0), nox.mathx.exp(0.0), nox.mathx.log(1.0), nox.mathx.pi() > 3.14159)
print(nox.mathx.min(2.0, 3.0), nox.mathx.max(2.0, 3.0), nox.mathx.abs(-1.5), nox.mathx.atan2(1.0, 1.0) > 0.78)

Output

4.0 1024.0 2.0 3.0
0.0 1.0 1.0 0.0 True
2.0 3.0 1.5 True

Edge cases follow IEEE-754: sqrt of a negative number is nan, log(0.0) is -inf, and nothing raises.

Which one?#

Prefer nox.mathx in new code. nox.math remains for existing code that calls the unqualified libm names. See nox.math for the comparison.
