# Conversion from binary to octal in vb.net

Vb program for Conversion from binary to octal. Here mentioned other language solution.

``````' Include namespace system
Imports System
'  Vb.net program for
'  Convert Binary number into Octal number
public Class Convert
' Convert decimal number into octal
Public Function  octal(ByVal number As Integer) As Integer
Dim result As Integer = 0
Dim multiplier As Integer = 1
Dim remainder As Integer = 0
while (number <> 0)
remainder = number Mod 8
result = (remainder * multiplier) + result
multiplier *= 10
number = (number / 8)
End While
Return  result
End Function
Public Sub binaryToOctal(ByVal num As String)
if (num.Length = 0) Then
' When empty binary number
Return
End If
' Some useful variable
Dim flag As Boolean = False
Dim decimalNo As Integer = 0
Dim counter As Integer = 0
Dim index As Integer = num.Length - 1
' We Assume that given binary number is valid
' Here - indicates negative binary number
' First convert binary to decimal
' Example = 10111 => 23
while (index >= 0)
if (num(index) = "1"c) Then
decimalNo += (1 << counter)
ElseIf (num(index) <> "0"c) Then
if (index = 0 AndAlso num(index) = "-"c) Then
' When get negative number
flag = True
Else
' Not a valid binary number
Return
End IF
End If
counter += 1
index -= 1
End While
' When given number is
Dim output As Integer = Me.octal(decimalNo)
if (flag = True) Then
output = -output
End If
' Display given number
Console.Write("Binary : " + num)
' Display result
Console.WriteLine(" Octal : " + output.ToString())
End Sub
Public Shared Sub Main(ByVal args As String())
Dim task As Convert = New Convert()
' Test Case
End Sub
End Class``````

Output

``````Binary : 1111 Octal : 27
Binary : 10111 Octal : 37
Binary : 101011 Octal : 153
Binary : 11011 Octal : 33
Binary : -1000110 Octal : -116``````
