# numrandom(1)

Print out a random number.

## 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.
