What it does

Web Crypto rejection sampling gives each integer in the inclusive range equal probability.

Worked example

Minimum 1 and maximum 6 simulate a six-sided die.

The example demonstrates the operation. For file-based tools, results depend on the selected file and options.

How the result is produced

Web Crypto rejection sampling gives each integer in the inclusive range equal probability.

Important limits

Range width at most 2^32. Random outputs naturally change when generated again.

Choosing the next step

Enter values in the units and convention named by the page, then compare the displayed formula with your question. For money, change the assumptions rather than treating an estimate as an offer; for statistics, decide whether the data represents a sample or a full population.
