Pick one random value or generate a list across a custom numeric range with Web Crypto-backed sampling.
Generate random integers or decimals with custom min and max values, quantity, precision, unique-value and sorting controls.
Integer mode draws whole numbers between the inclusive minimum and maximum. Decimal mode converts the requested precision into discrete numeric steps and draws from that finite range.
The generator supports up to six decimal places and can return one value or a larger list.
Enable Unique values only when duplicates are not acceptable. Toolmera checks that the requested quantity can fit inside the selected discrete range before generating.
Results can remain in random order or be sorted ascending or descending after generation.
Toolmera draws browser Web Crypto values and uses rejection sampling for bounded integer selection instead of a naive modulo operation.
This is a general-purpose utility and is not presented as a certified lottery, gaming or regulated drawing system.
Use the decimal random number generator when you need random values with fractional digits instead of whole integers. Set the minimum and maximum range, choose decimal output, select the required precision and generate one value or a list inside that range.
Decimal precision controls how many digits appear after the decimal point. This makes the generator useful for test data, simulations, examples and other workflows where a bounded random decimal value is more useful than an integer.
Open the tool and select the mode or options that match your task.
Provide the inputs required for the result.
Check the calculation, assumptions and supporting output shown by Toolmera.
Useful next steps in the same workflow.
Yes. Enable Unique values only; the tool validates whether enough distinct values exist in the selected range.
Yes. Decimal mode supports one to six decimal places.
The current interface accepts up to 10,000 generated values per run.
No. The current implementation derives bounded values from the browser Web Crypto API.
