The space was too small to place the necessary delay circuit.
Therefore, there are several bugs, such as incorrect calculations in some operations and -0 being displayed.
The overflow error detection circuit has also been temporarily deactivated due to frequent malfunctions.
We hope that the size of the space will be revised and widened or the size of the components will be reduced as soon as possible.
