I want to convert an array of single precision data into fixed point and I have proposed length of the data I want.

How to convert? All the searched answers are about the convertion flow of floating point function/algorithm/design to fixed point implementation.

Can I just convert the data?

Try calling the fi function.

q = fi(pi)
q =
