HiWord
Gets the second 16bit word of the operand.
result = HiWord( expr )
Returns the value of the high 16bit word of the low 32bit dword of expr.
This macro converts the numeric expression expr to an UInteger value, then expands to an UInteger representing the value of its second 16bit word - that is the most-significant (high) 16bit word of the least-significant (low) 32bit dword of expr.
The output would look like:
Syntax
Usage
result = HiWord( expr )
Parameters
Return Value
Returns the value of the high 16bit word of the low 32bit dword of expr.
Description
This macro converts the numeric expression expr to an UInteger value, then expands to an UInteger representing the value of its second 16bit word - that is the most-significant (high) 16bit word of the least-significant (low) 32bit 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)
Print "The binary representation of the MSW is "; Bin(HiWord(N))
Print "The binary representation of the LSW is "; Bin(LoWord(N))
Sleep
'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
The output would look like:
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
