c# regexp match

I have the regexp:

\[IN\](\d+)\[/IN\]

Which works fine for:

...[IN]34[/IN]...
...[IN]1[/IN]...
...[IN]12[/IN]...
etc

But it doesn't quite work for decimals, IE:

...[IN]3.5[/IN]...
...[IN]2.8[/IN]...
...[IN]9.4[/IN]...
etc

How do I make it match these as well?

Thanks!

Something like this

[IN](\d+|\d+\.\d+)?[/IN]

This ensures that you have a number after the dot if you have a dot.

From the top of my head i think it should be this:

[IN](\d+\.?\d*)[/IN]

EDIT: tested and corrected version:

\[IN\](\d+(\.\d+)?)\[\/IN\]

Try this -

\[IN\]\d+(\.\d+)?\[/IN\]

It doesn't check if it is valid float (have one decimal dot):

([\d.]+)
