two's complement

How do I convert a 16-bit hex number in two-complement notation into a signed decimal integer?  I've paid for the full version and cannot figure out how to do this.  Thanks, Steve

Hey Steve,

Since the calculator is in 32bit, you would enter the 16-bit hex number in two's compliment notation, then also invert the bits to the left to all 1s. A quick way to do this is to press the '!' to invert all of the bits first, then enter the 16-bit hex number accordingly. Let me know if this works for you.
