It uses JavaScript's
Math.random() combined with Math.floor() to produce a uniformly distributed integer within your specified range. The formula is: Math.floor(Math.random() × (max − min + 1)) + min.
Yes. Simply enter a negative value in the Min or Max field. For example, setting Min to −50 and Max to 50 will generate numbers in that full range, including zero and negatives.
It is pseudo-random, which is sufficient for the vast majority of everyday uses such as games, decisions, or giveaways. For cryptographic or security-critical applications, a hardware random number generator (HRNG) is recommended.
You can use any integers that JavaScript can safely represent — up to ±9,007,199,254,740,991 (Number.MAX_SAFE_INTEGER). For practical use, any everyday range works perfectly.
Common uses include picking lottery numbers, running raffles and giveaways, deciding who goes first in a game, sampling data for statistics, generating random IDs, and teaching probability concepts.
