Definitely, yes. log2, for instance. Another thing is functions like
sqrt() which can return double or complex results depending on the
input.
Most importantly, many m-functions are designed to be type-generic,
i.e. they will compute in double if passed double inputs, single with
single inputs, integers, complex, characters etc. How would you
reflect that with declarations?
