Question

Is there a maximum range of values passed in mt_rand() function? Is there a maximum ‘top’ number for it?

Do said limitations depend on platform?

Does mt_rand()‘s speed depend on the range passed in?

In other words, would mt_rand(0,100000000000000000000000000000000000000000000000) work?

Sorry for few questions in one.

Answer 1

returns a pseudo-random value between 0 and mt_getrandmax()

Why don’t you just call mt_getrandmax and find out? A commenter writes:

On both 32 and 64-bit systems (OS X and Linux), mt_getrandmax() returns 2147483647 for me, i.e. ~2^31.
