@feldhaus/math

@feldhaus/math

A lightweight math utility library that provides commonly used mathematical functions for JavaScript and TypeScript applications.

Installation

You can install the package via npm:

npm install @feldhaus/math

Available Functions

• clamp: Clamps a number between a minimum and maximum value. Source
• inverseLerp: Calculates the relative position of a value within a range. Source
• lerp: Linearly interpolates between two values. Source

Available Constants

• RAD2DEG: Conversion factor from radians to degrees 180 / Math.PI.
• DEG2RAD: Conversion factor from degrees to radians Math.PI / 180.
• HALF_PI: Half of Pi (π/2) Math.PI / 2.
• QUARTER_PI: Quarter of Pi (π/4) Math.PI / 4.
• TWO_PI: Two times Pi (2π) Math.PI * 2.
• TAU: Tau, which is equivalent to 2π Math.PI * 2.

Examples

import { clamp } from '@feldhaus/math';

const clampedValue = clamp(5, 1, 10); // Output: 5

import { DEG2RAD } from '@feldhaus/math';

const radians = DEG2RAD * 45; // Output: 0.7853981633974483

import { inverseLerp } from '@feldhaus/math';

const relativeValue = inverseLerp(10, 20, 15); // Output: 0.5

import { lerp } from '@feldhaus/math';

const interpolatedValue = lerp(0, 10, 0.5); // Output: 5
