There was an overflow in the calculations based on the input and the tool settings.
This typically occurs when an output value is very large, such as above the 32-bit signed maximum integer value of ~2.147 billion, or the 32-bit unsigned maximum integer value of ~4.295 billion.
Cells with values that exceed these limits will be returned as NoData.
If possible, avoid very large input values. You may be able to map your input values to a smaller range such that the operation being performed will not trigger this overflow.
Alternatively consider using smaller neighborhoods that don't contribute as many cells to each operation.
