High Quality RNG
|
The RAND() formula in Excel® and the Rnd() function in VBA use very simple algorithms to
generate pseudo-random numbers. In some Excel® versions, RAND() can even
generate negative numbers! If a high degree of randomness or a large quantity
of random numbers are required, these functions should not be used.
ZRandom uses the Mersenne Twister algorithm to generate pseudo-random
numbers, one of the best algorithms available. Mersenne Twister is very fast
and has a cycle period of 219937 - 1.
