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.
           -V  Increase verbosity.
           -d  Debug mode.  For developers

EXAMPLES

          Random number from 1 to 10.
           $ numrandom /1..10/
           7

          From 1 to 10 or from 15 to 20.
           $ numrandom /1..10,15..20/
           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/
           -0.8

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.
