# relativeError function

- dynamic calculated,
- dynamic correct

Returns relative error between `calculated`

and `correct`

.
The type of `calculated`

and `correct`

must match and can
be any vector, matrix, or quaternion.

## Implementation

```
double relativeError(dynamic calculated, dynamic correct) {
if (calculated is num && correct is num) {
final diff = (calculated - correct).abs().toDouble();
return diff / correct;
}
// ignore: return_of_invalid_type
return calculated.relativeError(correct);
}
```
