Casting numeric text to a floating point number then posting it back

I like your char.isDigit() solution for validating WinForm user input to numeric. How do you then cast the resulting numeric text to a floating point number and after processing (to a metric value for instance) post it back to a textbox.text with tostring(), but round to a reasonable number of digits?
ToString() receives an optional formatting string with which you can control the number of digits to use, etc. Take a look at the MSDN documentation for Double.ToString() for some examples.
