Problem with checking strings

[Markh51]

Hi,

I have a smal script which checks for the amount of figures either side of a decimal point:

decReg = "^[0-9]{"+lmin+","+lmax+"}\\.[0-9]{"+rmin+","+rmax+"}$"

lmin & lmax; define the amount of number that have to be on the left side of the point

rmin & rmax; same as above, but for the right side.

What I need to know, the above script makes the user enter the "." even if they put in a round figure, how can I change the above to mean: "only check the right hand side if the decimal point exists" ???

Thanks,
Mark

I don't think you'll be able to without split()ing the value at the "." position and then just validating that porition with the regex. unless you just want to set the pattern to accept any numeric amount in the whole numebr
"^[0-9]*\.[0-9]{"+rmin+","+rmax+"}$

what i really want is, if a user enters a decimal point then the script should only allow 2 figures after that.

How would I go about that ???

no, it's OK, the pattern you give me works fine for me.
