Draft 2

• Add a design decision section on the choice to return numbers from simplified calculations.

• Store interpolations as a separate data type so that they can be parenthesized when used in CalculationOperations.

• Throw errors when combining units that are known to be incompatible.

• Allow variables in CalcValues to return calculations.

• Define equality between calculations.

• Allow calculations in CSS color functions.

• Properly parenthesize the right-hand side of a / (b * c).

• Return calculations from meta.calc-args() as calculations, not unquoted strings.

• Return an unquoted string with value "calculation" from meta.type-of() for calculations, rather than a quoted string with value "calc".

• Allow calls to the global min() and max() functions in calculations.

• Allow clamp(var(--three-args)).

• Simplify calc(a + -b) to calc(a - b).

• Explicitly specify how calculations are parsed in plain-CSS mode.

• Allow numbers returned by simplifying calculations to create potentially slash-separated numbers.

• Fix some broken formatting.

• Remove TODOs about extra simplification.
