Syntax

#define LoByte( expr ) (Cast(UInteger, expr) And &h000000FF)

Parameters

NameDescription
exprA numeric expression, converted to an UInteger value.

Return value


Returns the value of the low byte of 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) byte.

Remarks

Usage


result = LoByte( expr )

Example


Dim N As UInteger



'Note there are 16 bits

N = &b1010101110000001

Print "N is                                       "; N

Print "The binary representation of N is          "; Bin(N)

Print "The most significant byte (MSB) of N is    "; HiByte(N)

Print "The least significant byte (LSB) of N is   "; LoByte(N)

Print "The binary representation of the MSB is    "; Bin(HiByte(N))

Print "The binary representation of the LSB is    "; Bin(LoByte(N))

Sleep


The output would look like:
N Is                                       43905
The Binary representation of N Is          1010101110000001
The most significant Byte (MSB) of N Is    171
The least significant Byte (LSB) of N Is   129
The Binary representation of the MSB Is    10101011
The Binary representation of the LSB Is    10000001
