> Using regular expressions how do I represent Floats. I'm not certain what you mean by that. Regex searches strings, so the only way floats would be recognised is if you had the string representation of them. Regex won't work with raw floating point data.
Assuming you do mean floating point numbers as strings then it depends again on the representation used in the string. NNNN.MMMM .MMMePPPP etc You have to look at the string pattern you are interested in and write a regex to match. The first form is the more common and searcging for a sequence of numbers followed by a literal period followed by another sequence of numbers is what you need. But then you might consider plus/minus signs in front etc. Can you show us what you tried?
