BITAND

BITAND 函數會傳回 2 個數字的按位元 AND。

BITAND(數值-1, 數值-2)

數值-1： 第一個數字數值-1 必須是整數。

數值-2： 第二個數字數值-2 必須是整數。

附註

數值可為任意順序，其會傳回相同的結果。
BITAND 的真值表如下：

數值-1	數值-2	BITAND(數值-1, 數值-2)
0	0	0
0	1	0
1	0	0
1	1	1

範例

=BITAND(9,13) 會傳回 9。9 的等效二進數為 1001，13 的等效二進數為 1101；位數符合最右側以及由右數來第四個位置。這會傳回 (2^0)+(2^3)，或是 9。

=BITAND(12,3) 會傳回 0。12 的等效二進數為 1100，3 的等效二進數為 11（也可以用 0011 表示）；位數不符合任何位置，因此傳回 0。
