C Math Functions

Syntax

#include <math.h>

double function(argument);

Example

#include <stdio.h>
#include <math.h>

int main() {
  double x = 16.0;
  double result;
  
  result = sqrt(x);
  printf("The square root of %lf is %lf\n", x, result);
  
  result = pow(x, 3);
  printf("%lf raised to the power of 3 is %lf\n", x, result);

  result = sin(x);
  printf("The sine of %lf is %lf\n", x, result);

  return 0;
}

Output

The square root of 16.000000 is 4.000000
16.000000 raised to the power of 3 is 4096.000000
The sine of 16.000000 is -0.287903

Explanation

The C Math Library provides various math functions, which can be used to perform mathematical operations. These functions are declared in the math.h header file.

Use

C Math functions can be used for a variety of applications, including calculating square roots, absolute values, exponents, trigonometric functions, and more. These functions can be used in a wide range of programs, including scientific computation, engineering, finance, and more.

Important Points

• Most of the C Math Library functions take double or float data types as input.
• The result provided by these functions is also of type double or float.
• The math.h header file should be included in the program to use these functions.
• Some commonly used math functions include sqrt(), abs(), pow(), sin(), cos(), and tan().
• These functions are often useful for complex calculations and can greatly simplify mathematical programming.

Summary

The C Math Library provides various mathematical functions that can be used for mathematical operations in the C programming language. These functions are declared in the math.h header file and can be widely used in many different types of programs. Understanding the syntax and use cases of these functions can greatly enhance the capabilities of a C programmer to perform complex calculations.
