LoByte

Returns the lowest byte of a number, bits 0 to 7.

Syntax

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

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) byte.

Return Value

Returns the value of the low byte of expr.

Remarks

Usage

result = LoByte( expr )

Dialect Differences

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

Differences from QB

• New to FreeBASIC

Examples

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
