Previously, these classes' equals() and hashCode() methods did not obey
the contracts:
For equals(), I considered two values equal even if there was a very
small deviation, in order to avoid floating-point error. This equals
relation is not transitive (i.e. it is possible that a = b && b = c but
a ≠ c), violating the contract of equals.
This also makes it impossible to properly implement hashCode, as if two
values are equal, they must have the same hash code. The solution I had
provided is an ineffective hack, which could mess with hash maps and
sets.
I have changed the implementation to demand exact equality. I have also
provided equalsApproximately() methods to both classes that use the old
behaviour. Hash codes are only really used for hash maps, and the old
implementation doesn't even achieve its purpose, so I did not add a
method to return the old hash behaviour.
Remove Unitlike/MultiUnit2025-05-31T00:54:19ZAdrien Hopkinsadrien.p.hopkins@gmail.com2025-05-31T00:48:42Zurn:sha1:e86fb71e1665cb9e8511bafd54df0fb8cbca5adc
I ended up never using this code - it was simpler to just use lists of
units and values. Making a whole new object for lists of units, and an
abstract class for things that convert things other than doubles, is
needlessly complicated, and doesn't solve any major issues. For
example, I still need to store each Unitlike type in a different
collection, because it will have a different type.

I specifically added tests for the methods that Jacoco says haven't been
tested:
- convertToMultiple
- equals
- equivalent
- hashCode
- operation methods
Show unit/dim file errors as popup2024-08-22T16:45:37ZAdrien Hopkinsadrien.p.hopkins@gmail.com2024-08-22T16:41:04Zurn:sha1:ea3e2bf07939926e43c7abe3fd13a7c4e93f69d1
Previously, any error in the unit or dimension file(s) crashes the
program. Instead, 7Units now ignores any invalid lines, still parsing
the correct ones, and shows a popup in case any errors happen.
