On the other hand, the divide is one expensive operation. The standard library takes 38uS to do the whole function call, up from 4uS on the 16MHz boards. I've been able to get the divide by 10 operation down to the point that the whole function call takes ~15.8uS.

WebWhen we divide a number x by 1 we need to arrive at the same number x. Of course, 1 is expressed as 1<<8 (or 256) in y because it has 8 bits for the fractional part. This means that when we divide a number x with a fixed point number y with the value 1, we will arrive at the same number x, but shifted right by 8!

"WebDescription. Shifts bits to the right. The number to the left of the operator is shifted the number of places specified by the number to the right. Each shift to the right halves the number, therefore each right shift divides the original number by 2. Use the right shift for fast divisions or to extract an individual number from a packed number.
