mathlib

Standard math library for XCX. Provides constants, arithmetic, trigonometry, statistics, geometry, combinatorics, unit conversion, and bit operations — all implemented in pure XCX with no external dependencies.

Installation

xcx pax add mathlib@latest

Usage

include "mathlib/math.xcx" as math;
f: area = math.circle_area(5.0);
f: root = math.sqrt_f(144.0);
f: angle = math.sin_f(math.PI / 4.0);
