public class ApcomplexField
extends AbstractField<ApcomplexField,Apcomplex>

This class represents an arbitrary precision complex number.

The precision of each calculation is determined separately, which means that loss of precision can easily accumulate in complicated calculations (e.g. matrix inversion). If this should be avoided, and a fixed precision is required, then it may be better to use FixedPrecisionApcomplexField instead.
