Performance when own functions are used

Short question,

If I use a stored function as an replacement for an oracle function like

CREATE OR REPLACE FUNCTION SP_SIGN (nBetrag IN NUMBER) return integer
as
begin

   return SIGN(NBETRAG);
end SP_SIGN ;
/

Does that decrease the performance or not? Regards
