Possible remaming of `num` and `den`?

[TotalVerb]

Could num and den be renamed to numerator and denominator? These function names are very unintuitive, and general policy is to avoid abbreviations unless they're very standard.

Sure, seems like a good idea.

Where is the problem? There could not be more intuitive names for these functions. When your are working with rational types, it is only natural to look for something like num or den. No need to make it too verbose.

Please keep the abbreviations. They are standard.

There could not be more intuitive names for these functions.

I disagree, numerator is more intuitive than num. This also has precedence from Python:

>>> from fractions import Fraction
>>> a = Fraction(16, -10)
>>> a.denominator
5
>>> a.numerator
-8

And Racket.

Can you cite some languages or libraries where this naming is used? Mathematica uses "Numerator" and "Denominator"; Python uses "numerator" and "denominator". Matlab doesn't have a standard way of representing or operating on rational numbers. R doesn't seem to either.

Ruby also uses numerator and denominator, as does C++ via Boost.

If anything, Julia appears to be the odd one out here.

[martinholters]

Add Haskell to the list for numerator and denominator.

[thofma]

Ok, convinced.
