; ********** round function **********
; C++ prototype:
; extern "C" int RoundD (double x);
; extern "C" int RoundF (float x);
; This function converts a single or double precision floating point number
; to an integer, rounding to nearest or even. Does not check for overflow.
; This function is much faster than the default conversion method in C++
; which uses truncation.
RoundD:
cvtsd2si eax, xmm0 ; Round xmm0 to eax
ret
;RoundD ENDP
RoundF:
cvtss2si eax, xmm0 ; Round xmm0 to eax
ret
;RoundF ENDP
