C sqrt Function

The C sqrt function is one of the Math Functions that is used to find the square root of a number or a specified expression. The syntax of the sqrt in this language is as shown below.

double sqrt(double number);

C sqrt Function Example

The math sqrt Function allows you to find the square root of a given number. In this program, We are going to find the square root and display the output.

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

int main()
{
    printf("\n The Square Root Value of 0       = %.4f ", sqrt(0));
    printf("\n The Square Root Value of 1       = %.4f ", sqrt(1));
    
    printf("\n The Square Root Value of 125     = %.4f ", sqrt(125));
    printf("\n The Square Root Value of 500.36  = %.4f ", sqrt(500.36));
    
    printf("\n The Square Root Value of -27.32  = %.4f ", sqrt(-27.32));  
    printf("\n The Square Root Value of -90     = %.4f ", sqrt(-90));
  
    return 0;
}

C Square root Example 2

In this C Programming example, we are allowing the user to enter their own value. Next, this program uses the math sqrt function to find the square root of the user given number.

TIP: Please refer to the cbrt, ceil(), and floor() functions article.

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

int main()
{
    float number, sqrtValue;

    printf(" Please Enter any Numeric :  ");
    scanf("%f", &number);
  
    sqrtValue = sqrt(number);
  
    printf("\n The Square Root of %.2f = %.4f ", number, sqrtValue);
  
    return 0;
}

 Please Enter any Numeric :  64

 The Square Root of 64.00 = 8.0000
