Problem ​

You need a random floating-point number within a specific range — for example jitter values, test data, or simulation inputs.

Solution ​

Use random(min, max) to get a number in [min, max].

ts
import { random } from '@vielzeug/arsenal';

random(0, 1); // e.g. 0.472
random(10, 20); // e.g. 14.83
random(-5, 5); // e.g. -2.1

Pitfalls ​

  • Uses Math.random() — not cryptographically secure. Use crypto.getRandomValues for security-sensitive use cases.
