Hello,

Out of curiosity, why do we have both Mathr::ZERO_TOLERANCE and 
Mathr::EPSILON in the code [*] ?

I would understand they're both intended to give an expected magnitude 
of rounding errors. (Note that ZERO_TOLERANCE is hardcoded as 1e-20, 
while EPSILON is ~ 2e-16 here)

Both are used throughout the code (EPSILON more often ?)


Thanks,

Jérôme
