Efficiency of Cartesian to Spherical coordinate conversion

[altenbach]

When debugging is disabled, most likely all you see is constant folding due to use of diagram constants (the result never changes so the compiler calculates it only once). You should also wire some output to prevent "dead code elimination". If the result is not used anywhere, all code leading to it is eliminated by the compiler.
