_complex usage in c language

The complex type is used to represent complex numbers in C language, including real and imaginary parts. Its initialization form is complex_number = 3.14 2.71i, the real part can be accessed through creal(complex_number), and the imaginary part can be accessed through cimag(complex_number). This type supports common mathematical operations such as addition, subtraction, multiplication, division, and modulo. In addition, a set of functions for working with complex numbers is provided, such as cpow, csqrt, cexp, and csin.

_,complex usage in C language

_,complex is used to represent plural numbers in C language type. It allows developers to easily handle numerical values ​​consisting of real and imaginary parts.

Basic Usage

_, Complex type variables can be initialized by specifying values ​​for the real part and imaginary part respectively. For example:

<code class="c">_Complex double complex_number = 3.14 + 2.71i;</code>

Among them, 3.14 is the real part and 2.71 is the imaginary part.

Accessing the real and imaginary parts

To access the real and imaginary parts of a complex number, use creal and cimag Macros.

• creal(complex_number) Returns the real part
• cimag(complex_number) Returns the imaginary part

Complex number operations

_, The complex type supports standard mathematical operators, including addition, subtraction, multiplication, division and modulus. The operation results are all values ​​of type _,complex.

Complex number functions

The C language standard library provides a set of functions for processing complex numbers, for example:

• cpow (complex_number, exponent): Find the power of a complex number
• csqrt(complex_number): Find the square root of a complex number
• cexp(complex_number) : Find the exponent of a complex number
• csin(complex_number): Find the sine of a complex number

Example

The following is Example of complex number arithmetic using the _,complex type:

<code class="c">_Complex double complex_a = 2.0 + 3.0i;
_Complex double complex_b = 1.0 + 4.0i;

_Complex double sum = complex_a + complex_b; // (3.0 + 7.0i)
_Complex double difference = complex_a - complex_b; // (1.0 - 1.0i)
_Complex double product = complex_a * complex_b; // (-11.0 + 14.0i)
_Complex double quotient = complex_a / complex_b; // (0.64 - 0.48i)</code>
