对两个表达式进行减法运算

语法

declare operator - ( byref lhs as integer, byref rhs as integer ) as integer
declare operator - ( byref lhs as uinteger, byref rhs as uinteger ) as uinteger

declare operator - ( byref lhs as single, byref rhs as single ) as single
declare operator - ( byref lhs as double, byref rhs as double ) as double

declare operator - ( byref lhs as T Pointer, byref rhs as T Pointer ) as integer
declare operator - ( byref lhs as T Pointer, byref rhs as integer ) as T Pointer

declare operator - ( byref lhs as T, byref rhs as T ) as integer
declare operator - ( byref lhs as T, byref rhs as integer ) as T
declare operator - ( byref lhs as integer, byref rhs as T ) as T

用法

result = lhs-rhs
