Dear GAP forum:
Is it possible to include default arguments in a function?
Such as something like this (which doesn't work):
add := function(a,b:=1)
return a+b;
end;
So that add(2,2) = 4 and add(2) = 3. The only way I've managed to do
is by writing:
add := function(arg)
if Size(arg) = 2 then
return arg[1] + arg[2];
else
return arg[1] + 1;
fi;
end;
But if you have 2 or 3 (optional) arguments with default values this
becomes cumbersome. Is there a more efficient way?
Best,
Kieran.
