# V6020. Division or mod division by zero.

The analyzer detected a potential division by zero.

Consider the following example:

    if (maxHeight >= 0)
    {
      fx = height / maxHeight;
    }

It is checked in the condition if the value of the maxHeight variable is non-negative. If this value equals 0, a division by zero will occur inside the if statement's body. To fix this issue, we must ensure that the division operation is executed only when maxHeight refers to a positive number.

The fixed version of the code:

    if (maxHeight > 0)
    {
      fx = height / maxHeight;
    }

This diagnostic is classified as:

CWE-369 CERT-NUM02-J
