Utils

This object provides helper functions used for seeding arrays of integers or longs.

The seeding functions are an adaptation/port of code from the the 32-bit and 64-bit implementations of MersenneTwister (MT19937.c, MT19937-64.c).

MersenneTwister is a fast, 623-dimensionally equidistributed pseudo random number generator with a 2¹⁹⁹³⁷ - 1 long period.
