Dear GAP-developers,
I do not really like the function name "IsRat" for the check if an object
is a rational number
and suggest to introduce the synonym "IsRationalNumber" :
DeclareSynonym("IsRationalNumber",IsRat);
What is your opinion?
Jakob
GAP as a number of short names for such common categories like e.g. `IsInt',
`IsPosInt', `IsCyc',
`IsBool', `IsFFE', `IsChar', `IsPerm' etc., so to my mind `IsRat' fits this
naming scheme quite
well. These are used in many method installations and having compact names
is quite handy.
The page http://www.gap-system.org/Faq/Usage/usage1.html explains how to
customise GAP using the
.gaprc file, so if you prefer this synonym for your personal use, you may
add this line there.
Of course, any code using it will not work without this declaration.
Best wishes,
Alexander

Jakob has a point here. IsRat is a question about your mouse, not about a
number. ;)
I have a hamster and tried IsRat on him.
Hamster:=1; # I have one hamster
[ 1
IsRat(Hamster);
[ true
