percent

Problem

You need the percentage one value represents of a total — for example computing "what % of users are active?"

Solution

Use percent(value, total) to return (value / total) * 100.

import { percent } from '@vielzeug/arsenal';

percent(1, 4); // 25
percent(3, 4); // 75
percent(0, 100); // 0

Pitfalls

• Returns NaN when total is 0.
