-
For numbers, the comparison uses numerical value.
-
For strings, the comparison is conventional string equality (same length and contents).
-
For bitsets, the sets must be equal. It is an error if the comparands do not have the same capacity.
-
For all other types, the comparands are compared by address, meaning that they are equal if and only if they are one and the same object in memory.
