@arki/math/roots

Every result carries an error estimate, and a method that misses its tolerance throws a ConvergenceError subclass holding its best estimate (.best) instead of returning a wrong number. A function that returns NaN or Infinity throws NumericRangeError naming the point. derivative and limit are numerical estimates, not proofs.

The same page covers @arki/math/roots. For integrate see integrate; for derivative and limit see differentiate.

import { findRoot } from '@arki/math/roots';
 
findRoot(x => x ** 3 - 2 * x - 5, [2, 3]).root; // 2.094551481542327   Brent, bracket must change sign
