Complex number library written in and for C.
This simple C library allows you to easily manipulate complex numbers by creating math functions that are made specifically for complex numbers.
- Elementary operations with complex numbers (addition, substraction, multiplication, division)
- Exponentiation of complex numbers
- Square root function
- Degrees to radians conversion and viceversa
- Conjugate of a complex number
- Real and imaginary part of a complex number
- Convert a complex number type (
complex_t) to a string.
- Modulus of a complex number (absolute value)
- Polar coordinates of a complex number
To import the library, simply add #include "complex.h" to the file. All functions will be imported and you'll now be able to use the library.
The complex number data type is defined as complex_t, which is a struct with 2 long double data types: the real part and the imaginary part. Although it is possible to change the individual values of the complex_t data type, it is recommended to use the built-in functions.
In this documentation,
complex_t means the complex data type,
long double is a real number, and
char* is a C null-terminated string.
These are all the functions with the corresponding description and arguments:
char* ctoa(complex_t)
Convert complex number to a string, in format a+bi or a-bi.long double degtorad(long double)
