\modulesynopsis{General floating point formatting functions.}

The \module{fpformat} module defines functions for dealing with

floating point numbers representations in 100\% pure

Python. \strong{Note:} This module is unneeded: everything here could

be done via the \code{\%} string interpolation operator.

The \module{fpformat} module defines the following functions and an

exception:

\begin{funcdesc}{fix}{x, digs}

Format \var{x} as \code{[-]ddd.ddd} with \var{digs} digits after the

point and at least one digit before.

If \code{\var{digs} <= 0}, the decimal point is suppressed.

\var{x} can be either a number or a string that looks like

one. \var{digs} is an integer.

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 like

one. \var{digs} is an integer.

Return value is a string.

\end{funcdesc}

\begin{excdesc}{NotANumber}

Exception raised when a string does not look like a number when the

documentation says it should.

\end{excdesc}

Example:

\begin{verbatim}

\end{verbatim}
