numrandom(1)
NAME
numrandom - 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.
OPTIONS

16 - An even number from 0 to 10
- $ numrandom /0..10i2/
4 - An odd number. Notice the starting number in the range.
- $ numrandom /1..10i2/
9 - A factor of 3 between 99 and 120.
- $ numrandom /99..120i3/
111 - A decimal number.
- $ numrandom /1.1..2.5i0.1/
1.8 - A negative random number.
- $ numrandom /0.0..-2.0i0.3/

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.
