[Phpwm] unsigning a numeric variable

[Paul at Black Hill]

Hello
 
I'm a newcomer to the site so please forgive me if I post messages
incorrectly (and please tell me how to do it properly!)
 
Am I missing something obvious, or can you simply use the abs() function to
obtain the absolute value of the number? This could be combined with the
function is_numeric() to do the validation on user input that you need.
 
I hope this helps
 
Regards
Paul
