TMDSCNCD28335: IQ mathematics descirtion

Part Number: TMDSCNCD28335

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).
