"""
Handles backports of the standard library's `fractions.py`.

The fractions module in 2.6 does not handle being instantiated using a
float and then calculating an approximate fraction based on that.
This functionality is required by the FITS unit format generator,
since the FITS unit format handles only rational, not decimal point,
powers.
