Web1) The fsin instruction is ONE instruction! The sin routine is (at least) thousand instructions! Even if the fsin instruction itself is "slow" it should be thousand times faster than the complicated routine gcc calls. 2) The FPU is at 64 bits mantissa using gcc, i.e. fsin will calculate with 64 bits mantissa and NOT only 53 as SSE2.
