require-math

require-math is an extension of JavaScript's built-in Math Object. It allows you to work with geometric formulas, 2D-shape formulas, and basic math calculations. Try it out with Node.js npm: https://www.npmjs.com/package/require-math github: https://github.com/jesushilarioh/require-math
