What is Random Decimal Number Generator

Last reviewed:

Decimal (base 10) is the everyday number system humans use, handy as a reference format when converting between binary, octal, and hexadecimal values.

Random Decimal Generator mints random floating-point numbers in an inclusive-exclusive range with a configurable number of decimal places.

Paste `min max` on the first line (e.g. `0 100`) and pick precision in the toolbar. Great for Monte Carlo seeds, test fixtures, and statistical simulations.

Why use it

  • Seed Monte Carlo or statistical simulations.
  • Populate sliders and numeric inputs with test data.
  • Mock sensor readings for UI prototypes.
  • Generate fixture values for numeric validators.
  • Build demo charts with plausible ranges.

Features

  • Inclusive-min / exclusive-max range
  • Precision 0-15 decimal places
  • Up to 10,000 values per batch
  • Uniform distribution
  • Local-only Random Decimal Number processing keeps data in-browser

How to use Random Decimal Number Generator

  1. Enter range. Type 'min max' (e.g. 0 100).
  2. Set precision. Pick decimal places.
  3. Run. Copy the list.

Example (before/after)

Input

0 1

Output (precision=4, count=3)

0.2837
0.9145
0.5062

Common errors

Missing range

Input needs 'min max'.

Fix: Provide both numbers separated by space or comma.

min >= max

Invalid range.

Fix: Use a strictly increasing range, e.g. 0 100.

FAQ

Is the range inclusive?

min is inclusive; max is exclusive (standard Math.random() semantics).

What precision is supported?

0 to 15 decimal places.

How many per batch?

Up to 10,000 decimals.

Is it statistically uniform?

Yes — uniform over [min, max).

Is input uploaded?

No — decimals are sampled from Math.random in your browser and never transmitted.
