libmpdec is an example of numerical code.  I don't think anyone but you has argued that is_integer() is useless in numerical code.  Whether it is float or decimal doesn't matter.

I get the API-bloat argument, but I'm completely surprised that anyone would assert the above.


I think searching GitHub or the Internet for robust numerical code is not conclusive.  80% of open source stuff is probably derived from netlib anyway. :-)



I'll avoid giving examples outside of libmpdec because I don't have time for a nitpicking war. :-)
