i see, my bad
i can't believe there is no way of finding out if a value is a valid number without using a script or recursion
so what would be a valid number?
5
5.123
0.5
.5
0.0
1.0e+5
123,456
123,456.789
123 456
123 456.789
(same with minus sign)
am i missing any and is taking into consideration the formatting with "," and " " overkill?
