NAME

Number::Ops - Simple operations on numbers.

SYNOPSIS

use Number::Ops qw(:all);

DESCRIPTION

This contains a number of very simple number operations.

ROUTINES

randomize, random
use Number::Ops qw(:all);
randomize;
$val = random($range);

Randomize initializes the random number generator. It will be called automatically if it is not called explicitly. Also, it will only initialize the random number generator one time per session.

Random returns an integer in the range 0 ... $range-1.

min, max
use Number::Ops qw(:all);
$value=min(@list);
$value=max(@list);

Returns the numerical minimum/maximum value of all arguments.

isnum, isint
use Number::Ops qw(:all);
$flag=isnum($string [,$low, $high]);
$flag=isint($string [,$low, $high]);

isnum returns 1 if $string is a valid real number with no exponent, 0 otherwise. If $low is entered, $string must be >= $low. If $high is entered, $string must be <= $high. It is valid to check only one of the bounds.

isint is similar but checks integers.

round
$value = round($num [,$dec]);

Rounds to the closest integer or to $dec number of decimal places.

KNOWN PROBLEMS

None at this point.
