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. Ranges are inclusive.
OPTIONS
-h Help: You're looking at it.

-d Debug mode. For developers

4
An odd number. Notice the starting number in the range.
$ numrandom /1..10i2/
9

$ 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.
