Random Number Generator

Enter a minimum and maximum, then select Generate number. The result will fall within the range allowed by your bounds and selected decimal precision.

Open More options to generate as many as 1,000 values, prevent duplicate results, choose between 0 and 6 decimal places, or display the generated numbers in ascending or descending order.

After generating the result, use Generate again for a new selection or Copy to place each number on a separate line in your clipboard.

When Decimal places is set to 0, the generator works with whole numbers and includes both the minimum and maximum. A range from 1 to 100 contains 100 eligible integers and can return either 1 or 100.

The number of possible integers is the maximum minus the minimum, plus one. The extra one accounts for both endpoints. For example, 5 through 8 contains four values: 5, 6, 7, and 8.

Ranges that cross zero include zero as an eligible value. A range from -5 to 5 therefore contains 11 integers, not 10.

Decimal mode selects values from an exact fixed-precision grid. One decimal place uses steps of 0.1, two decimal places use steps of 0.01, and six decimal places use steps of 0.000001.

For example, a range from 1.12 to 1.18 with two decimal places contains seven eligible values: 1.12, 1.13, 1.14, 1.15, 1.16, 1.17, and 1.18.

The tool selects directly from this grid rather than generating an unrestricted decimal and rounding it afterward. Generated results are displayed with the exact number of decimal places selected, including trailing zeros such as 2.50.

A decimal boundary can be selected only when it fits the chosen precision. The lower bound moves inward to the first eligible grid value, while the upper bound moves inward to the final eligible grid value.

For example, with a minimum of 1.123, a maximum of 1.138, and two decimal places, the only eligible result is 1.13. Values such as 1.12 fall below the minimum, while 1.14 exceeds the maximum.

Some narrow ranges contain no value at the selected precision. A range from 1.121 to 1.129 has no two-decimal value inside it, so the tool asks you to widen the range or increase the decimal precision.

The size of the eligible pool matters when you request several unique numbers. Integers from 1 through 10 provide 10 possible values. Decimals from 0.1 through 0.5 at one decimal place provide five values.

A range from 0 to 1 at two decimal places contains 101 possible values because it includes 0.00, 1.00, and every 0.01 step between them.

When Unique values is enabled, the requested count cannot exceed the number of eligible values. For example, the generator can create five unique integers from 1 through 5, but it cannot create six.

When Unique values is turned off, every draw can use the complete eligible range. A number selected earlier can therefore appear again in the same result.

Repeated values are a normal part of independent random selection. They do not automatically indicate that the generator is stuck, biased, or malfunctioning.

For example, generating ten numbers from 1 through 3 will necessarily include repeats because only three possible values exist.

Turn on Unique values when every generated result must be different. Once a value is selected, it is excluded from the remaining draws in that generation.

This is similar to drawing numbered cards without returning each card to the container. The available pool becomes smaller after every selection.

Uniqueness applies only to the current result. A number generated previously can appear again after you select Generate again.

Choose Ascending to display values from smallest to largest or Descending to display them from largest to smallest. Choose Keep generated order when the original selection order matters.

Sorting changes only the order in which the results are displayed. It does not generate a different set of values or make particular numbers more likely.

For example, a generated order of 42, 7, and 19 becomes 7, 19, and 42 when sorted ascending. If those values represent first, second, and third selections, keep the generated order instead.

Both the minimum and maximum can be negative. A range from -20 to -10 generates values entirely below zero.

You can also use a range that crosses zero, such as -10 to 10. In integer mode, zero and both endpoints are eligible.

When sorting a mixed negative and positive result, ascending order places the most negative values first, while descending order places the largest positive values first.

Use one generated integer to select a numbered student, question, page, task, seat, participant, or game action. Make sure the minimum and maximum match the numbering system you are using.

Generate several unique integers for a draw order, sample rows, practice questions, numbered tickets, or a subset of items from a larger numbered list.

Fixed-precision decimals can provide placeholder measurements, prices, percentages, coordinates, test inputs, or mock spreadsheet data. Generated values should be reviewed before being used in any real analysis or published dataset.

Do not request more unique values than the range contains. A range from 1 through 5 cannot produce six different integers.

Choose enough decimal places for the interval you entered. A narrow range may contain no eligible two-decimal value even though it contains many mathematical decimals.

Keep the generated order when selection sequence matters. Sorting removes the original first-to-last draw order.

Do not assume a repeated number is an error when Unique values is disabled. Independent selections are allowed to produce the same result more than once.

Remember that inclusive ranges count both endpoints and that a range crossing from a negative number to a positive number also contains zero.

Range validation, random selection, uniqueness checks, sorting, formatting, and copying are handled in your browser. Your settings and generated numbers are not sent to a server or added to the URL.

The generator uses browser-provided Web Crypto random values when available and maps them to the eligible integer or decimal grid.

This tool is suitable for ordinary choices, games, classroom activities, examples, testing, and informal sampling. It is not a physical-randomness service, an independently audited drawing platform, a reproducible seeded generator, or a tool for creating passwords, encryption keys, recovery codes, or other security-sensitive values.
