log10 Arithmetic function in C Language

log10 Arithmetic function in C Language

In this tutorial, we will discuss about  log10 Arithmetic function in C Language

Description

In the C programming language, the log10() Arithmetic function in C Language returns the logarithm of x to the base of 10

log10(): In C programming Language,log10() function is use to perform  calculate natural logarithm

 

Declaration

The Syntax for the log10() Arithmetic function in the C Language is

double log10(double x);

Parameters or Arguments

x is the parameter or argument of this function used to calculate the logarithm of x to the based of 10

 

Return value

The log10() function returns the logarithm of value to the base of 10

 

Required Header

In C Language,the required header file for log10() function is

#include<math.h>

Example

The example shows usage of the log10() function

Program 1

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

int main()
{
    double x,y;
    x=1.5;
    y=2.5;
printf("log10 value of %f is: %f\n",x,log10(x));
printf("log10 value of %f is: %f",y,log10(y));
getch();
    return 0;
}

 

When we compile above program,it will produce the following result

log10 value of 1.500000 is: 0.176091

log10 value of 2.500000 is: 0.397940

 

 Program 2

#include <stdio.h>
#include <math.h>
int main()
{
    //define temporary variable
    double value1;
    double result;
    printf("Enter the number for value1 :");
    //get input from user
    scanf("%lf",&val1);
    //calculate log10
    result=log10(val1);
    //Display log10 value
    printf("log10 value of %lf is: %lf\n",value1,result);
getch();
    return 0;
}

When we compile above program,it will produce the following result

Enter the number for value1 :1.5
log10 value 0f 1.500000 is :0.176091
