LOWORD

Gets the least-significant word (LSW, or lo-word) of an Uinteger value.

Syntax:#define Loword( expr ) ( Cast(Uinteger, expr) and &h0000FFFF )
Usage:result = Loword( expr )
Parameters:

expr

A numeric expression, converted to an Uinteger value.

Return Value:

Returns the LSW value of `Cast(Uinteger, expr)`.

Description:

This macro converts the numeric expression expr to an Uinteger value, then expands to an Uinteger representing the value of its LSW.

Examples:

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

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
