std/math

The Math module provides a core set of standard mathematical constants and functions. It acts as a Zen-C wrapper around the standard floating-point mathematical operations.

Overview

• Static Methods: All methods are called on the Math struct directly.
• Precision: Uses double for high-precision floating-point arithmetic.
• Comprehensive: Covers trigonometry, exponentials, logarithms, and rounding.
• Efficient: Directly wraps optimized C library functions.

Usage

import "std/math.zc"

fn main() {
    let radius = 5.0;
    let area = Math::PI() * Math::pow(radius, 2.0);
    println "Area of circle: {area}";
}

Constants

All constants are static functions returning a double.

Constant	Description
Math::PI()	Archimedes' constant (approximately 3.14159).
Math::E()	Euler's number (approximately 2.71828).
