== Type-generic macro ==
A type generic macro is something which allows calling a function whose type is determined by the type of argument in the macro. This means, for example, x is declared as an [[int(computer science)|int]] data type but [[tangent|tan]] has been called this way:<br />
tan((float)x)<br />
then this expression will have a type [[floating point|float]].
