发帖数: 6806 | 2 9 Many binary operators that expect operands of arithmetic or enumera-
tion type cause conversions and yield result types in a similar way.
The purpose is to yield a common type, which is also the type of the
result. This pattern is called the usual arithmetic conversions,
which are defined as follows:
--If either operand is of type long double, the other shall be con-
verted to long double.
--Otherwise, if either operand is double, the other shall be converted
