How to use Random number generator.

01

Set the range

Choose the minimum and maximum values, then decide whether the result should use integers or decimals.

02

Choose the quantity

Generate one value, a unique set, or allow repeats when the same number may be drawn more than once.

03

Select the method

Use secure browser randomness for ordinary draws, a seed for repeatable results, or the wheel for a visible sequence.

04

Keep the record

Copy the numbers and review the settings, time and result details when the draw needs to be explained.

Ways to use Random number generator.

Three different ticket numbers

For tickets numbered 1 through 100, set those limits, request 3 integers, and enable No repeats. If ticket numbers have gaps, use a list picker instead of a continuous range.

Ten worksheet values

Choose integers from 1 to 20 and request 10 values. Allow repeats for independent samples, or enable No repeats when each exercise must use a different value.

Decimal practice data

Choose Decimal, limits of 0 and 1, and 2 decimal places for values such as 0.27 or 0.84. These are examples, not a prediction of the next generated set.

Repeatable demonstrations

Enter a seed such as lesson-1 and keep the same range, quantity, precision, and repeat settings. Regenerating that setup reproduces the sequence; changing a setting can change the result.

Before you use the result.

Generate 1–1,000 values per request; Decimal mode supports 0–8 decimal places. Unique values must fit the chosen range and precision. A seed reproduces a setup, not an unpredictable draw. The SHA-256 record helps compare recorded data, but it is not an independent audit or proof that an organizer did not generate several draws and select one.

Continue with the next fair draw.
