while trying to learn about IQ maths. i came across example by TI in C28x%20IQmath%20Library.pdf
Compute Y = 5*X in IQ26 format.
_iq26 Y, X;
long M;
M=5; // M=5
X = _IQ26(5.1); //X=5.1 in IQ29 format
Y = _IQ26mpyI32(X,M); // Y=25.5 in IQ29 format
if I understand correctly Y value in IQ29 is in the range of (-4,4).
