hi
how to convert the Y = typecast(uint32(X), 'uint32') to real no.
for example I want to calculate the present velocity for dynamixel servo motor. it is suppose to be -16
but each time I calculate it, I got this no. (4294967278)![velocity.png](https://www.mathworks.com/matlabcentral/answers/uploaded_files/221667/velocity.png)

Well, how do you "calculate" it? It sounds like you initially read a number as unsigned integer and now want a signed integer instead. Perhaps, the simple fix is to read the number properly as a signed integer avoiding the problem in the first place.

>> typecast(uint32(4294967278),'int32')
ans = -18

What do you mean by "real number"? Do you mean you want it in the double data type? If so call double on it. If you mean something else, please clarify.
