This is not equivalent. I don't remember the details, but in the making
of Ada 95 there was a furious discussion between numericists about
whether it was possible to make a discrete random generator given a
floating point random generator.

After megabytes of E-mail discussion, they concluded that NO, it was not
possible, and therefore that Ada should have both.
