Can I generate both integers and decimals with these tools?

Yes, most of the listed generators support whole numbers and fractional values, though the level of precision and control over decimal places varies by tool.

Is the randomness cryptographically secure?

Only RapidTables explicitly states it uses a cryptographically secure pseudorandom number generator in the browser; the others rely on standard pseudo-random algorithms.

How many numbers can I generate at once?

Quantity limits differ: RapidTables caps list length at 16,384, while Calculator.net and PineTools allow you to specify how many unique numbers you need without a stated maximum.

Can I set a custom minimum and maximum range?

Yes, all five tools let you define a minimum and maximum boundary for the output, giving you control over the range of generated values.

Do these tools show any kind of distribution or results history?

RapidTables includes a distribution graph that visualizes number occurrences, while the other tools focus on generating new numbers each time without built-in history tracking.

Buyer's guide

How to choose a random number generator

When picking a random number generator, first decide whether you need whole numbers, decimals, or both — some tools specialize in one format. Next, consider how many numbers you need and whether you want options to control duplicates, sorting, or decimal precision. If security matters (e.g., cryptography or simulations), look for a tool that mentions cryptographically secure generation, as not all do.
