numrandom - Print out a random number.
numrandom [-dhV] /[expression]/
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.
-h Help: You're looking at it. -V Increase verbosity. -d Debug mode. For developers
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
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.
