negative numbers

[markfc]

is there a quick php command for making a number negative?

i.e. from 25.23 to -25.23 ?

Thanks

$num = 0 - $num;

It's called simple fricking arithmetic... multiply by -1 or subtract from 0, it woudl be utterly pointless to make a function just to turn a number negative.

Unless it also checked to make sure a number as negative before acting like ABS does for positives. However this is very simple

function NBS($num) {
if ($num > 0) { return $num * -1;}
return $num
}
