Convert unsigned 16bit to signed 32bit

Hello
I am after a way of efficiently converting an unsigned 16 bit integer to a signed 32 bit one. Speed is key in my application. Thanks.

Uhhh....

unsigned int16 x;
signed int32 y;

x=0x1234;
y=x;

you could also do:

y=make32(0,x); -- but I'm not sure how it handles signed values. Since I've never tried it.

Thanks for the reply. I was really looking for code that would include the scaling, i.e. mid value of the unsigned variable would translate to zero of the signed variable. Anyway, I found a work around the issue. Thanks again.

Ahh,

You didn't say that.

It's usually good to be specific when you have needs that are out of the ordinary.
