topic ATAN within [0,2pi) in Software Archive https://community.intel.com/t5/Software-Archive/ATAN-within-0-2pi/m-p/930816#M14757 I want to take the arctangent of y/x, with the output in the range [0,2pi). Is there a more elegant way than using <BR /> <BR />angle = AMOD(ATAN2(y,x)+TWOPI,TWOPI) <BR /> <BR />where I have defined TWOPI as a parameter?
