Remarks

SSE Option("SSE") indicates that a floating point value (Single or Double) returned from a function is stored in the xmm0 register. Option("Sse") is ignored unless the source is compiled with the -fpu SSE command line option. This option may be used immediately after the return type in a function declaration or function definition. This option is an optimization only and not required to compile programs using the -fpu SSE command line option. Declare Function ValueInXmm0 () As Double Option("sse") FPU Option("FPU") indicates that a floating point value (Single or Double) returned from a function is stored in the st(0) register. This option may be used immediately after the return type in a function declaration or function definition. Declare Function ValueInStZero () As Double Option("fpu") Differences from QB
