Math Function in C? With Example

 Math Function in C

C Programming allows us to perform mathematical operations through the functions defined in <math.h> header file. The <math.h> header file contains various methods for performing mathematical operations such as sqrt(), pow(), ceil(), floor() etc.

Math Functions

There are various methods in math.h header file. The commonly used functions of math.h header file are given below.

No.	Function	Description
1)	ceil(number)	rounds up the given number. It returns the integer value which is greater than or equal to given number.
2)	floor(number)	rounds down the given number. It returns the integer value which is less than or equal to given number.
3)	sqrt(number)	returns the square root of given number.
4)	pow(base, exponent)	returns the power of given number.
5)	abs(number)	returns the absolute value of given number.

Math Function Examples

include <math.h> 
int main() 
{ 
// Basic arithmetic operations

    int a = 5, b = 3;
int sum, diff, product, quotient, remainder; 
 sum = a + b; 
 diff = a - b;
 product = a * b;
 quotient = a / b;
 remainder = a % b;
printf("Basic Arithmetic Operations:\n"); 
printf("Sum: %d\n", sum); 
printf("Difference: %d\n", diff); 
printf("Product: %d\n", product); 
printf("Quotient: %d\n", quotient); 
printf("Remainder: %d\n", remainder); 
// Power function 
double base = 2.0, exponent = 3.0; 
double result_pow = pow(base, exponent);
printf("\nPower Function:\n"); 
printf("Result of %.2lf raised to the power %.2lf: %.2lf\n", base, exponent, result_pow);
// Square root function 
double num_sqrt = 25.0; 
double squareRoot = sqrt(num_sqrt); 
printf("\nSquare Root Function:\n"); 
printf("Square root of %.2lf: %.2lf\n", num_sqrt, squareRoot);
// Trigonometric functions

    double angle = 45.0; 
double radian = angle * M_PI / 180.0; // Convert angle to radians 
double sineValue = sin(radian); 
double cosineValue = cos(radian);
double tangentValue = tan(radian); 
printf("\nTrigonometric Functions:\n"); 
printf("Sine of %.2lf degrees: %.4lf\n", angle, sineValue); 
printf("Cosine of %.2lf degrees: %.4lf\n", angle, cosineValue); 
printf("Tangent of %.2lf degrees: %.4lf\n", angle, tangentValue); 
return 0;
