Hello I am doing timing phase correction in a QPSK system. Given a maximum power timing phase I need to round down to nearest 100.
Example:
If I get 568, I want to get 500.
Round(568,-2) gives 600. I need to always round down. What do you all suggest?

Divide by 100, then floor() or fix() (depending on how you want to handle negative numbers), then multiply by 100.
x = 568;
floor(x/100)*100
fix(x/100)*100
x = -568;
floor(x/100)*100
fix(x/100)*100
