Oct Function 

Returns a string representing the octal value of a number.


Public Shared Function Oct( _
   ByVal Number As { Byte | SByte | Short | UShort | _
   Integer | UInteger | Long | ULong | Object } _
) As String

Parameters

Number

Required. Any valid numeric expression or String expression.

Exception type Error number Condition

ArgumentNullException

5

Number is not specified.

ArgumentException

5

Number is not a numeric type.

See the "Error number" column if you are upgrading Visual Basic 6.0 applications that use unstructured error handling. (You can compare the error number against the Number Property (Err Object).) However, when possible, you should consider replacing such error control with Structured Exception Handling Overview for Visual Basic.

If Number is not already a whole number, it is rounded to the nearest whole number before being evaluated.

If Number is Oct returns

Empty

Zero (0)

Any other number

Up to 22 octal characters

You can represent octal numbers directly by preceding numbers in the proper range with &O. For example, &O10 is the octal notation for decimal 8.

This example uses the Oct function to return the octal value of a number.

Dim TestOct As String
' Returns "4".
TestOct = Oct(4)
' Returns "10".
TestOct = Oct(8)
' Returns "713".
TestOct = Oct(459)
