I am using this square root function from within my C++ application. But I am a little bit worried that it might not be totally fail safe. Can it in some way "screw it up" for other applications that uses the FPU at the "same" time? How should I fix it if that's so?

(Toggle Plain Text)

.586
.model flat, C

.code

sqrt proc x:DWORD
	fld x
	fsqrt
	ret

sqrt endp

end

Thanks for your help!
