Deprecated since version 2.6: The fpformat module has been removed in Python 3.
The fpformat module defines functions for dealing with floating point numbers representations in 100% pure Python.
Note
This module is unnecessary: everything here can be done using the % string interpolation operator described in the String Formatting Operations section.
The fpformat module defines the following functions and an exception:
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.
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 raised when a string passed to fix() or sci() as the x parameter does not look like a number. This is a subclass of 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'
