Hi,

At mp-math.mpxl:167 there is:
vardef atan primary x = angle(1,x) enddef ;
The MetaPost manual says:
The angle operator takes a pair and computes the two-argument
arctangent; i.e., angle is the inverse of the dir operator
So it looks like "angle" is the function that you want for "atan2".
Thanks,
