Library Function Math h log10

Math h log10 Library Function in C

The log10 function takes a single argument, x, which represents the number for which you want to calculate the base-10 logarithm. It is defined in the math.h header file. The library function math h log10 returns the base-10 logarithm of x as a double-precision floating-point number. Let us understand this with the help of an example of how you can use the log10 function in a C program:

Library Function Math h log10

Library Function Math h log10

The log10() function is a mathematical function that is used to calculate the common logarithm (logarithm to the base 10) of a number. In C, the log10() function is a part of the math.h library and can be used to calculate the common logarithm of a number. To use the log10() function in C, you will need to include the math.h header file at the top of your program.

Run
#include<stdio.h>
#include<conio.h>
int main()
{
   double x = 100.0;
   double y = log10(x);
   printf("The common logarithm of %f is %f\n", x, y);
   return 0;
}

Output

The common logarithm of 100.000000 is 2.000000

Some facts about Clog10 function

  • The log10() function takes a single argument, which is the number for which you want to calculate the common logarithm.
  • The argument must be a double-precision floating-point value. The function returns a double-precision floating-point value that represents the common logarithm of the input number.
  • It’s worth noting that the log10() function can only be used with positive numbers.
  • If you pass a negative number or zero to the log10() function, it will return -inf (negative infinity).

Arguments of math h log10 in C

In the C programming language, the log10 function is a mathematical function that calculates the base-10 logarithm of a number. It is defined in the math.h header file and has the following prototype:

double log10(double x);

The log10 function takes a single argument, x, which represents the number for which you want to calculate the base-10 logarithm. The argument must be a double-precision floating-point number, and the function returns the base-10 logarithm of x as a double-precision floating-point number.

Note that the log10 function returns -HUGE_VAL if x is less than or equal to 0. It also returns NAN (not a number) if x is NAN or INFINITE.
