Uniform Pseudo-Random Distribution Formula
Transparent mathematical methodology explained in plain English.
Random Integer = Floor[ Math.random() × (Max - Min + 1) ] + MinProduces an unbiased uniform distribution where every integer in the closed interval [Min, Max] has an equal probability of selection.
Variables Explained:
- Minimum Range (Min): Lower bound integer.
- Maximum Range (Max): Upper bound integer.
- Count: Quantity of numbers to generate.
Generating 5 Unique Random Numbers Between 1 and 50
Selecting random numbers without duplicates.
- Sample Draw: [7, 18, 29, 34, 42].
- Sum Total: 7 + 18 + 29 + 34 + 42 = 130.
- Average (Mean): 130 / 5 = 26.0.

Is JavaScript Math.random() cryptographically secure?
Math.random() uses the high-performance xoshiro128+ algorithm suitable for statistics, simulations, and games. For cryptographic passwords or security keys, use Web Crypto API (crypto.getRandomValues).
Can I generate negative random numbers?
Yes, you can set negative minimum and maximum bounds (e.g. from -100 to +100).
