Hi all,

I want to use a regular expression statement in my asp.net 1.1 project to validate float numbers which can have ", . " as floating seperators. I am new in this topic, please help me.

Thanks in advance.

Thank you very much OriginalGriff it works perfectly for floating point numbers, but there is one more problem. I want integers to be included in this control, I forgot to add them into the question :(

This regex should work for int as well. Did you try?

Um - it won't! :laugh:

:-( . Yup requires ? or probably * will also do, right?
OriginalGriff 16-Nov-12 6:48am
   
? - Yes.
* - No.
"*" would allow 1.2,2.2.2,2

Add a question mark to the end: that makes the last part optional with zero or one repetitions:
[+-]?\d+([\.\,]\d+)?
