What is math.h and why do we use?

By | May 15, 2023

math.h is a header file in the C Standard Library, which is commonly used in C programming. It is designed for basic mathematical operations.

This header file defines a set of functions and macros that provide mathematical functions capabilities for C programs. Some of the most commonly used functions in math.h are sqrt, log, sin, cos, tan, exp, pow, abs, ceil, floor, and fmod. These functions are used to perform mathematical operations in C programs. It is one of important header file and used in many C programs.

In general, the functions in stdio.h provide a convenient and portable way for a C program to perform input and output operations. To use the functions defined in stdio.h, you need to include the header file at the beginning of your source code file, like this:

#include <math.h>

By including math.h in your code, you have access to a wide range of mathematical functions that can be used to calculate squre root, logarithm, sin, cos, tan, exponential, power, absolute value, remainder etc.
