Description & Motivation
Converted all adders to use the same base Adder class with a conditional carry input (Logic? carryIn).
Related Issue(s)
None
Testing
Most adders are now tested uniformly in the adder_test.dart file using both carry and non-carry configurations.
Backwards-compatibility
Yes. The FullAdder no longer has a carryOut, it is in sum[1]. Otherwise, other adders now have an optional carryIn.
Documentation
Yes. All adder documentation has been updated to reflect the change.
