cplxintro Introduction to complex mathematics in C++

This section contains an overview of the classes, functions and operators provided by the C++ complex math library.

---

#include <complex.h>
class complex;

---

Declarations for all complex math operators and functions are contained in the <complex.h> header file.

The data type for complex numbers is implemented as a class named complex.

Overloaded versions of the following operators and math functions are available for processing complex numbers:

• standard input/output operators and arithmetic, assignment, and comparison operators; see section "cplxops Operators"
• standard math functions such as exponential, logarithmic, power, and square root functions; see section "cplxexp Transcendental functions"
• trigonometric functions (sine, cosine, hyperbolic sine, and hyperbolic cosine); see section "cplxtrig Trigonometric and hyperbolic functions".

Routines to convert between Cartesian and Polar coordinate systems are discussed in section "cplxcartpol Cartesian/Polar functions".
Error handling is described in section "cplxerr Error handling functions".
