Random Number Generator

Generate random integers or decimals with count, range, decimal precision, and uniqueness options.

Inputs

Defaults are prefilled so the result is visible immediately.

Minimum

Maximum

How many numbers

Decimal places

Unique values

Results

Results update as the calculator inputs change.

Generated numbers

97, 36, 29, 99, 8

Count generated

Range

1 to 100

Formula and Assumptions

Each value is sampled uniformly from min + random() x (max - min), then rounded by decimal setting.

Use the recalculate button on the page to draw a fresh set without editing inputs.

Unique decimal values are generated by retrying until the requested count or retry limit is reached.

Reference Upgrade

Built from the Calculator.net model, with added context.

Live validation and instant result updates instead of a submit-only workflow.

Multiple decision metrics are shown together, not only the primary answer.

Formula notes and assumptions are visible on the page so the math is easier to audit.

Reference Model

Modeled after the input style and primary output on Calculator.net's Random Number Generator.

The page keeps the math in one place and exposes the assumptions beside the result.

Default inputs: min=1, max=100, count=5, decimals=0, unique=false
