RE: Floating point bug in Canon F-789SGA
Floating point bug is actually a "feature" (put inside intentionally).

Without this "feature", they might get many customer complains:

It is hand-holding feature for people don't understand floating point.
They expected sqrt(4) - 2 = 0, not some tiny tiny number.

But, allowing calculator to "fix" the values, the final result is not as precise.

The medicine is worse than the cure ...
