PowerShell $hash1+2 Output InvalidOperation: A hash table can only be added to another hash table. 雖然加法運算子非常有用,但請使用指派運算符將元素加入哈希表和數位。 如需詳細資訊,請參閱about_Assignment_Operators。 下列範例會使用+=指派運算符,將專案新增至陣列: ...
Also, the AEC-to-WebAssembly compiler supports the operators +=, -=, *= and /=, with the same meaning as they have in C. For example, the following code in the x86 dialect of AEC: i := 0 While i < n | i = n If i = 0 fib(i) := 0 ElseIf i = 1 fib(i) := 1 ...

This library gives javascript coders a way to handle operators with a single statement() => aVec * bVec - dVec. The calculation can be combined with numbers() => aVec * bVec * 4 - dVec - 1.5. Vector objects can be create with numbernew Vector(5, 6, 7)or directly with assigned ...
