Real and Imag.
DoubleComplex supports equality operations, conversion from type double or a string representation, and basic arithmetic operations. Static member functions are also provided for returning the argument (or phase) of a complex number, the complex conjugate, the norm (or modulus), and for converting from polar coordinates.
Trigonometric functions for complex numbers, and mathematical functions such as exponents, logarithms, powers, and square roots, are available in class NMathFunctions.
