Arithmetical Library Function In C

C function where are used to perform mathematical   operations program are called arithmetical function.  This library are inbuilt in arithmetical function in c language.

“math.h” and “stdlib.h” header files support all the arithmetical function in c language.

List of arithmetical function given below:

1.pow()

2.sin()

3.sqrt()

4.log()

Fig: arithmetical library in c 

1.pow()

This is used to find power of given number.

Program

#include<stdio.h>

#include<conio.h>

#include<math.h>

void main()

{

int     i,n,j;

printf(“Input two number”);

scanf(“%d %d%d”, &I,&j,&n);

n=pow(I,j);

printf(n);

getch();

}

Output:

Input two value

5

3

125

2.sin()

This function is used to calculate  sine value.

Program

#include<stdio.h>

#include<conio.h>

#include<math.h>

void main()

{

int     i,n;

printf(“Input  number”);

scanf(“%d %d%d”, &I);

n=pow(I);

printf(n);

getch();

}

Output:

Input  value

90

0

3.sqrt()

This f unction is used to find the square root of the argument  passed to  this function.

Program

#include<stdio.h>

#include<conio.h>

#include<math.h>

void main()

{

int     i,n;

printf(“Input  number”);

scanf(“%d %d%d”, &I);

n=sqrt(I);

printf(n);

getch();

}

Output:

Input  value

25

5

4.log()

This function is used to calculate  the natural logarithm.

Program

#include<stdio.h>

#include<conio.h>

#include<math.h>

void main()

{

double  n,x;

x=72.325;

n=log(x);

printf(n);

printf(x);

getch();

}

Ouput:

72.325
