FIX16Mul

This function multiplies two signed 16-bit fixed-point numbers. The numbers do not have to have the same resolution (number of decimal places). The resolution of the number with the higher number of decimal places is reduced before the multiplication, i.e. the decimal places of the number with the higher resolution are truncated. The result of the multiplication is a signed 16-bit fixed-point number.
