Regexp adds decimal points?

I'm trying to use Michael Todd's patch for translating and sending MSC light commands but the float I send to it gets modified and 5 decimal points are added to the value. This makes the patcher unusable as it converts all these points and ends up llonger than the 9 value limit of the sxformat object. Is this a new bug in MAX or am I missing something?

Copy patch and select New From Clipboard in Max.

here is the problematic part, see how the 90.1 suddenly becomes 90.099998

If you Google something like "float precision site:cycling74.com" you will find gazillions of posts explaining the workings of binary floating point. It's not actually a Max issue, it's nothing new, and it's a feature not a bug.

Peter Elsea's tutorial on the subject is highly recommended.
