获取操作数的第二个16位字。
语法
用法
result = HiWord( expr )
参数
返回值
返回值为expr 的低32位双字的高16位字的值。
说明
该宏将数值表达式
expr 转换为
UInteger值,然后扩展为
UInteger,表示其第二个16位字的值,即最不重要(最低)16位字的最低有效(高)16位字)32bit双字
expr .
例子
Dim N As UInteger
'Note there are 32 bits
N = &b10000000000000011111111111111111
Print "N is "; N
Print "The binary representation of N is "; Bin(N)
Print "The most significant word (MSW) of N is "; HiWord(N)
Print "The least significant word (LSW) of N is "; LoWord(N)
Print "The binary representation of the MSW is "; Bin(HiWord(N))
Print "The binary representation of the LSW is "; Bin(LoWord(N))
Sleep
输出将如下所示:
N Is 2147614719
The Binary representation of N Is 10000000000000011111111111111111
The most significant word (MSW) of N Is 32769
The least significant word (LSW) of N Is 65535
The Binary representation of the MSW Is 1000000000000001
The Binary representation of the LSW Is 1111111111111111
