The 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 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 NotANumber
- 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'
