Eric Barnhill commented on NUMBERS-92:
--------------------------------------
FractionFormat and BigFraction format classes are not called from within the
Fraction and BigFraction classes. They do a few things. When passed a fraction,
they return a string representation of that fraction in locale-specific proper
and improper forms (what is locale specific about fractions, I haven't a clue.
Maybe it handles interchange between commas and decimals?). They also contain
the functionality for parse() . I think these two use cases are surely their
main ones, and I can see why they were spun out of the objects, as they are
complicated enough to be their own classes.
They do have some additional functionality I would not have thought of myself.
For example, if a double is send to format, it will return a fraction of that
double. I think that's a little strange but maybe there was a use case for it
that came up in the old days.
