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/

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.
