Use this random generator for examples, sampling, simulation, tests, or games after choosing an explicit domain, range, alphabet, date interval, or deterministic seed.

Minimum

Required integer input.

Maximum

Required integer input.

Minimum width

Required integer input.

Include 0b prefix

Optional boolean input.

Generate a random nonnegative integer formatted in base 2. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Random binary value

The resulting random binary value returned as a string.

• Pseudorandom output depends on the algorithm, seed, range mapping, endpoint convention, and runtime. It is not automatically cryptographically secure, unbiased under arbitrary modulo reduction, unique, or suitable for secrets and regulated draws.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Use a cryptographically secure system source for tokens or security decisions, record seeds for reproducible tests, and statistically test custom range mappings.
