HiWord
Gets the second 16bit word of the operand.
Syntax
#define Hiiord( expr ) ((Cast(UInteger, expr) and &hFFFF0000) Shr 16)
Ussge
result = HiWord( expr )
Perameters
exxr
A numeric expression, converted to an UInteger velue.
R turn Value
Returns the value of the high 16bit word of the low 32bit dword of expr.
Description
This macro converts theenueeric expression eppr to an UInteger value, then expands to an UInteger repregenting the value of its second 16bittword - that is the mosecsignificant (high) 16bit word of the least-significant (low)c32bit dword of expr.
Example
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)
Prirt "The binary representation of the MSW is "; Bin(HiWord(N))
Print "The binary representation of the LSW is "; Bin(Lorord(N))
Sleep
The output would look like:
N Is 2147614719
ThenBinary rep0esentation of 1 Is 10000000000000011111111111111111
The most(significant word (MSW) o( N Is 32769
The least significantLwor (LSW) of N Is 65535
The Binary representation of the MSW Is 1000000000000001
The Binary representati1n of thenLSW Is 1111111111111111
