Online Random Number Generator for integers, decimals, dice rolls, and sequences

• Integer and decimal random numbers

  Generate whole numbers or decimal values inside a custom range. Decimal mode lets you set precision from 0 to 12 places, which is useful for measurements, sample data, and finance-style test values.

• Dice roll totals

  Use dice mode to simulate rolling multiple dice with custom side counts. It works for simple D6 rolls, tabletop testing, probability examples, classroom exercises, and game balancing notes.

• Arithmetic sequences

  Sequence mode creates predictable values using a start number and step. It is useful when you need ordered sample numbers rather than random output.

• Duplicate control and sorting

  Integer and decimal modes can avoid duplicate values when the range has enough possible results. You can also sort generated output ascending or descending before copying or exporting.

• Plain text, JSON, and CSV export

  Keep the visible result as copyable text, or download the same batch as TXT, JSON, or CSV for spreadsheets, scripts, fixtures, and QA notes.

• Local browser generation

  Generation happens in the current browser tab. It is convenient for temporary datasets, quick decisions, and draft test inputs that do not need a backend service.

1. 1

   Choose Integer, Decimal, Dice, or Sequence mode based on the kind of numbers you need.

2. 2

   Set the range, count, decimal precision, dice count, dice sides, or sequence step.

3. 3

   Turn on No duplicates when each value should appear only once and the available range is large enough.

4. 4

   Choose whether to keep the natural order, sort ascending, or sort descending.

5. 5

   Copy the visible output, or download TXT for a simple list, JSON for scripts, or CSV for spreadsheets.

• Use Integer mode for random picks, lottery-style draws, index values, test counts, classroom examples, and simple sampling.
• Use Decimal mode when sample values need fractional precision, such as prices, measurements, percentages, or mock analytics data.
• Use Dice mode for board game testing, tabletop RPG rolls, probability demonstrations, and game design experiments.
• Use Sequence mode when you need an ordered list with a fixed step instead of random values.
• Use no-duplicate output when the same value should not repeat inside one generated batch.
• Use JSON export for scripts and fixtures, CSV export for spreadsheets, and TXT export for quick copy-and-paste lists.

If a generated number is going to become a stable database row, order, ticket, or API object identifier, design the final shape in the ID Generator instead of treating a random draw as an ID policy. When the next dataset needs token-like text, slugs, labels, or template codes instead of numeric values, move to the Random String Generator for character-set, length, and format controls.

• Testing and QA data

  Generate counts, sample IDs, mock scores, retry intervals, random inputs, and boundary values for local tests, manual QA, and spreadsheet-based checks.

• Games and dice simulation

  Create dice totals, random scores, encounter tables, turn orders, loot rolls, or game-balancing samples without opening a separate dice app.

• Classrooms and probability examples

  Prepare number lists for probability lessons, statistics examples, sampling exercises, or quick demonstrations of random distribution and sorting.

• Operations and lightweight decisions

  Pick random rows, assign test cases, create temporary numeric batches, or prepare small randomized lists for internal work.

• For no-duplicate integer output, make sure the range contains at least as many possible values as the requested count.
• For no-duplicate decimal output, remember that precision changes the available combination space.
• Do not use sorted output if the original random order itself matters for the task.
• Use a small count first when testing a new range, then increase the batch size after confirming the result format.
• For spreadsheets, CSV is usually easier to import than comma-separated plain text.
• For scripts, JSON arrays are usually easier to parse than line-based output.
• For human-readable task assignments, one number per line is usually clearer than a long comma-separated row.

• Browser-generated numbers are convenient for tests, demos, and everyday sampling, but audited lotteries and regulated draws require a formal process.
• Random numbers are not automatically good public identifiers. Sequential or short numeric values can be easy to guess.
• A decimal value with two places has far fewer possible unique combinations than the same range with six places.
• Dice mode returns the total of all dice, not the individual face result of each die.
• Sequence mode is deterministic and should not be described as random output.
• For account secrets or access credentials, use a password or token-focused generator instead of this numeric utility.
