Random Number = Min + floor(Random() × (Max − Min + 1))
Frequently Asked Questions
Is this truly random?
+
This uses JavaScript's built-in pseudo-random number generator, which is suitable for general use like games and simple decision-making, but not for cryptographic security.
Can I generate negative numbers?
+
Yes, simply set your minimum value to a negative number, and the generator will include negative numbers in the possible results.
Are both minimum and maximum values included?
+
Yes, this generator is inclusive on both ends — if you set 1 to 10, both 1 and 10 are possible results.
