numrandom(1)
Print out a random number.
SYNOPSIS
numrandom [-dhV] /[expression]/
DESCRIPTION
numrandom
will print out a random number determined by the expression that you give. The
syntax and program is nearly identical to the numrange program, except that numrandom
picks a number at random from the range expression. If no expression is specified,
numrandom will print out a random integer between 1 and 100.
Ranges are inclusive.

BUGS
numrandom is slow when dealing with large ranges to randomly
find a number from. This is because it creates a list of all
potential numbers before picking one. So it can be memory intensive
for large ranges.
