+:mod:`fpformat` --- Floating point conversions
+==============================================
+
+.. module:: fpformat
+   :synopsis: General floating point formatting functions.
+.. sectionauthor:: Moshe Zadka <moshez@zadka.site.co.il>
+
+
+The :mod:`fpformat` module defines functions for dealing with floating point
+numbers representations in 100% pure Python.
+
+.. note::
+
+   This module is unneeded: everything here could be done via the ``%`` string
+   interpolation operator.
+
+The :mod:`fpformat` module defines the following functions and an exception:
+
+
+.. function:: fix(x, digs)
+
+   Format *x* as ``[-]ddd.ddd`` with *digs* digits after the point and at least one
+   digit before. If ``digs <= 0``, the decimal point is suppressed.
+
+   *x* can be either a number or a string that looks like one. *digs* is an
+   integer.
+
+   Return value is a string.
+
+
+.. function:: sci(x, digs)
+
+   Format *x* as ``[-]d.dddE[+-]ddd`` with *digs* digits after the  point and
+   exactly one digit before. If ``digs <= 0``, one digit is kept and the point is
+   suppressed.
+
+   *x* can be either a real number, or a string that looks like one. *digs* is an
+   integer.
+
+   Return value is a string.
+
+
+.. exception:: NotANumber
+
+   Exception raised when a string passed to :func:`fix` or :func:`sci` as the *x*
+   parameter does not look like a number. This is a subclass of :exc:`ValueError`
+   when the standard exceptions are strings.  The exception value is the improperly
+   formatted string that caused the exception to be raised.
+
+Example::
+
+   >>> import fpformat
+   >>> fpformat.fix(1.23, 1)
+   '1.2'
+
