C Double Data Type Explained

In the C language, double is a type of floating-point data used to store double-precision floating-point numbers. Double type is typically used to store a larger range of floating-point numbers, providing higher precision.

Double type variables can store decimal numbers with double precision, meaning they have higher accuracy than float type. Typically, the storage space occupied by double type is 8 bytes.

Here is an example using the data type double:

#include <stdio.h>

int main() {
    double num1 = 3.14;
    double num2 = 5.678;
    double result = num1 + num2;

    printf("The sum of %f and %f is %f\n", num1, num2, result);

    return 0;
}

In the example above, we defined two double type variables, num1 and num2, calculated their sum, stored it in the result variable, and then printed out the result.
