The RDZ command initializes the xoroshiro128+ (v1.0) pseudo-random number generator with a seed.

The same seed will generate always the same pseudo-random sequence, provided internal precision is the same.

This command is fully compatible with userRPL.

The following program

« 32 SETPREC
  -1 RDZ
  RAND
»

will result in

1:                0.437333743646
