4 in your code is not a float. It's an integer.

I need to convert float numbers into a string in a certain way[1]. The
original string looks like:


I need to convert it into:


so all floating point numbers n need to be replaces by @"n". Can you
suggest a good way to do that?

My main problem is to define a pattern for searching that matches all
floating point numbers, but not e.g. '4+5.2' in the above example.

Is it possible with lua or do I need the lpeg extension?

Thank you very much!

[1] I need to do that because I use RiscLua which supports floating point
numbers only as userdata.
