int length in vba code example

Example 1: vba make a short integer from two bytes

Public Function MakeInteger%(LoByte As Byte, HiByte As Byte)
  If HiByte And &H80 Then
    MakeInteger = ((HiByte * &H100&) Or LoByte) Or &HFFFF0000
  Else
    MakeInteger = (HiByte * &H100) Or LoByte
  End If
End Function

Example 2: excel-vba get integer high byte

LoByte = n And &HFF					'<-- if n is a 2-byte Integer (left byte)
HiByte = (n And &HFF00&) \ &H100	'<-- if n is a 2-byte Integer (right byte)
