It isn't clear exactly what your initial condition is so I can't answer for sure.
Overall, though, you can't answer for sure. If the value is unsigned it's positive no matter what. If it's signed and the high bit is 1 it's negative. If the high bit is 1 you have to know how the program is going to interpret it to know whether it's positive or negative.
If your 8A45 is a 16-bit signed number it's negative. If it's 32-bit it's positive. If it's unsigned it's positive.
