Hello,

I have found this values and dont understand how the scaling is done:

512 /* 1.0 scaled as 22,9 */
16 /* 1.0 scaled as 27,4 */
32 /* 0.0625 scaled as 22,9 */
 

I'm gonna give myself the answer.

512 /* 1.0 scaled as 22,9 */
I think it means that the most semnificative 22 bits are used to represent the integer part, and 9 bits to represent the fractional part. In the case above 512/(2^9)=1
