# V6020\. Division or mod division by zero\.

The analyzer detected a potential division by zero\. 

Consider the following example:

```cpp
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:

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