Python's math.exp in TypeScript

How to use

Install via yarn add locutus and import: import { exp } from 'locutus/python/math/exp'.

Or with CommonJS: const { exp } = require('locutus/python/math/exp')

Use a bundler that supports tree-shaking so you only ship the functions you actually use. Vite, webpack, Rollup, and Parcel all handle this. For server-side use this is less of a concern.

Examples

These examples are extracted from test cases that automatically verify our functions against their native counterparts.

#	code	expected result
1	exp(0)	1
2	exp(1)	2.718281828459045

Notes

• Returns e raised to the power of x
