Safe code?

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?

.586

.model flat, C



.code



sqrt proc x:DWORD

        fld x

        fsqrt

        ret



sqrt endp



end

Thanks for your help!

Err, well Intel says it's FPU is really reliable. It won't "screw it up" for other applications because the operating system will take care of it - it should save the state of the CPU and FPU before switching to a different application.
