No need to check if nDX is 0 for atan2
We rely on IEEE floating-point arithmetic anyway, and then even both
arguments equal to 0 do not result in an error.
Even if it was different, it would be better to check id both nDX and
nDY are 0, and return 0 early.
It was so ever since "MWS_SRX644: migrate branch mws_srx644 -> HEAD"
commit fd2cf3dc7cd9c73070fa4d70c8ca99c9fc1ce135.
