LoWord

Returns the lowest 16 bits of a number.

Syntax

#define LoWord( expr ) (Cast(UInteger, expr) And &h0000FFFF)

Parameters

  • expr

Description

This macro converts the numeric expression expr to an UInteger value, then expands to an UInteger representing the value of its least-significant (low) 16bit word.

Return Value

Returns the value of the low word of expr.

Remarks

Usage

result = LoWord( expr )

Dialect Differences

  • Not available in the -lang qb dialect unless referenced with the alias __LOWORD.

Differences from QB

  • New to FreeBASIC

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
