Compare Two Arbitrary Precision Numbers

I slapped together min() and max() functions using bccomp(). While min() and max() only take an arbitrary number of args (i.e. max(1, 5, 1235, 12934, 66)) bccomp only takes 2.

Note that this doesn't take into account $scale.

<?php

function bcmax() {
$max = null;
foreach(func_get_args() as $value) {
if ($max == null) {
$max = $value;
} else if (bccomp($max, $value) < 0) {
$max = $value;
}
}
return $max;
}

function bcmin() {
$min = null;
foreach(func_get_args() as $value) {
if ($min == null) {
$min = $value;
} else if (bccomp($min, $value) > 0) {
$min = $value;
}
}
return $min;
}
?>
