The same concerns apply to decimal.  It makes sense to have the operation (for both binary and decimal floating-point) as “Type.remainder(a,b)” or a free function like "remainder(a, b)”, but I would prefer not to use the operator “%” for it because it behaves very differently from integer %, and in ways that are not at all obvious to most users.
