How to Check if a Double Variable Represents an Integer?

Verifying Integer Status of Double Variables

In programming, it may be necessary to determine if a double variable represents an integer value. While the provided code syntax isn't correct, the goal is to identify this condition efficiently.

One approach to testing the integrality of a double is through mathematical comparison:

if (variable % 1 == 0) {
    // Integer value
}

The modulo operator (%) calculates the remainder of the division operation. When dividing a double by 1, an integer result will have a remainder of 0. By comparing this remainder to 0, you can establish whether the double is equivalent to an integer.
