Imports System

Module ExabyteExample

    '
    ' VB.NET Long is a signed 64‑bit integer.
    ' Maximum value: 9,223,372,036,854,775,807  (~9.22 × 10^18)
    '
    ' Exabyte sizes:
    '
    '   1 EiB = 2^60  = 1,152,921,504,606,846,976 bytes
    '   1 EB  = 10^18 = 1,000,000,000,000,000,000 bytes
    '
    ' Both values fit safely inside a Long.
    '

    ' Binary exabyte (exbibyte), using a bit shift.
    ' 1L << 60 = 2^60 bytes.
    Public Const EXABYTE_EIB As Long = 1L << 60

    ' Decimal exabyte (SI), using a readable numeric literal.
    Public Const EXABYTE_EB As Long = 1_000_000_000_000_000_000L

    Sub Main()
        Console.WriteLine("1 EiB = " & EXABYTE_EIB & " bytes")
        Console.WriteLine("1 EB  = " & EXABYTE_EB  & " bytes")
    End Sub

End Module



' run:
'
' 1 EiB = 1152921504606846976 bytes
' 1 EB  = 1000000000000000000 bytes
'
