Return value is a string.\end{funcdesc} \begin{funcdesc}{sci}{x, digs}Format \var{x} as \code{[-]d.dddE[+-]ddd} with \var{digs} digits after the point and exactly one digit before.If \code{\var{digs} <= 0}, one digit is kept and the point is suppressed. \var{x} can be either a real number, or a string that looks likeone. \var{digs} is an integer. Return value is a string.\end{funcdesc} \begin{excdesc}{NotANumber}Exception raised when a string passed to \function{fix()} or\function{sci()} as the \var{x} parameter does not look like a number.This is a subclass of \exception{ValueError} when the standardexceptions are strings.  The exception value is the improperlyformatted string that caused the exception to be raised.\end{excdesc} Example: \begin{verbatim}>>> import fpformat>>> fpformat.fix(1.23, 1)'1.2'\end{verbatim}
