Well, the data represents the number of black pixels in certain zones in a binary image ..
The data is an input to a neural network for classification which requires a normalized input in the range of -1 to 1!

Well, i tried Kaz's method in C, the fixed point representation as displayed in hex format doesn't match the value!! What I did is multiply the floating point number by 1024 (10 bit fraction accuracy) and cast to integer .. it didn't match

Why don't you post a couple of examples of the number of black pixels, the corresponding value in floating-point normalized to between -1.0 and 1.0, and then the corresponding 10-bit Q0.9 format number.
I suspect by the time you repeat this, you will realize your mistake.
