Testing for a valid decimal number


Recommended Posts

:o I was wondering if there is a way or an option or if anyone knows of a script i can use. I want to test a particular number (decimal) to make sure it is vaild. I want to make sure that the number of decimals after you enter in a number is not more than 2 decimals places... ex XXX.xx ... I want to be able to set it up so that when it is invalid i can display an error message. The error message I got but to test to make sure that there are no more than 2 decimal places I do not. Any help would be appreciated

Try this:

Variable Set Integer %N1% from Position of Text in Variable %T1%
Variable Modify String: Copy Part of %T1% to %T2%
Variable Set Integer %N2% from Length of Variable %T2%
If Variable %N2% > 3
 Text Box Display: Error: Two many decimal digits
 Macro Stop
 Text Box Display: OK
End If
