I understand I can use the function isdigit() to check if a char has the value 0-9, but what about floats? I have a float that I would like to verify contains only digits and the ".". Is there some function that will do this?
Maybe I am overanalyzing this

I don't think so (could be wrong though) but you can make your own easily.

ispunct will check for punctuation characters
