Compares two JSON values for equality according to the following rules:
- Two JSON values are equal if (1) they are from the same type and (2)
their stored values are the same.
their stored values are the same according to their respective
`operator==`.
- Integer and floating-point numbers are automatically converted before
comparison. Floating-point numbers are compared indirectly: two
floating-point numbers `f1` and `f2` are considered equal if neither
`f1 > f2` nor `f2 > f1` holds.
`f1 > f2` nor `f2 > f1` holds. Note than two NaN values are always
treated as unequal.
- Two JSON null values are equal.
@note NaN values never compare equal to themselves or to other NaN values.
