with odd.
It is widely considered to be one of the most ill-conceived random number generators designed. Notably, it does not have a full period, due to the poor choices of modulus and multiplier; it also fails the spectral test badly for dimensions greater than 2.
- ...its very name RANDU is enough to bring dismay into the eyes and stomachs of many computer scientists! --Donald Knuth
