Public bug reported:
Binary package hint: gcalctool
In programming mode:
Bitwise operations AND/OR/XOR all fail with "Invalid bitwise operation"
if one of the operands is 0
XNOR exhibits the following behavior using decimal and 16 bit operand:
1 XNOR 0 returns 65534
0 XNOR 1 returns "Invalid bitwise operation"
This appears to be the case regardless of base used or operand size
Haven't tested the NOT operator
