Complex utility functions if imaginary part is 0

[axkr]

Are there some similar utility functions for the Complex number type as in the Guava DoubleMath utility class, if the imaginary part is 0.0?

There are not (yet) similar functions in Complex. We have added quite a large number of functions so Complex now implements the new CalculusFieldElement interface, for the sake of solving issue #67. The closest function to your second need would be round, but it is in the RealFieldElement interface, not in the CalculusFieldElement class. We could move it up as explained in the comment I wrote here.

We could implement the first method directly in Complex, without reference to any higher level interface.
