• The object $f remains unchanged.
• All methods except fcmp return a number string (nstr) of the form /[+-]\d+E[+-]\d+/, with embedded whitespace ignored.
• A return value of NaN indicates either that an input parameter was "Not a Number" or that an illegal operation was attempted.
• A similar default scale value is computed for square roots.
