May be worth trying something using the "preg_match()" function. With the first
example you had I was able to get that to work with the following. Though I did
just catch the potential for "501", so it needs a littel more tweaking.
$var = '8-15@113.5';
if(preg_match('/^[1-5]*[0-9]*[1-9]+\-[1-5]*[0-9]*[1-9]+\@[1-9]+[0-9.]*$/',
$var))
{
}
