Question:
This one may look rather strange as a requirement to be achieved in abap, but that's because it is part of a BW project, so not really dealing with the commonly used concepts in SAP.
I need to do conversions between degrees and radians and vice-versa. Basically, with the longitude and latitude of two points on the globe, I am able to calculate the so called Great Circle Distance.
I think this is not achievable in abap, as I don't find enough mathematical instructions.
To tell it more clearly, this is the JAVA instruction I try to reproduce :
return 60.0d * Math.toDegrees(Math.acos( Math.cos(latA) * Math.cos(latB) * Math.cos(dLong) + Math.sin(latA) * Math.sin(latB)));
Do anybody have an idea to help me ?

It has been a while since I was in school but
isnt the relation of RAD & DEG not as follows?
RAD = pi/180* DEG.
PI could be defined as a constant and sin and cos do exist as function - so you should be fine...

You're right. Thanks for this !
