Low impact, just info on how to prevent panic errors cause by division by zero
Take a look at uintDiv():
As seen, this function is used to divide an unsigned int in this case u by a fixed number f, but currently the only check applied to the uintDiv() function in regards to the divisor f is:
if (f < 0) revert InvalidFixedPoint();
The above means that a value of 0 would get accepted for f which would result in a panic error.
Make changes to the uintDiv() function
