Octfunction

Converts a number to octal representation

String Functionsfunctiondocumented

Syntax

Declare Function Oct ( ByVal number As UByte ) As String
Declare Function Oct ( ByVal number As UShort ) As String
Declare Function Oct ( ByVal number As ULong ) As String
Declare Function Oct ( ByVal number As ULongInt ) As String
Declare Function Oct ( ByVal number As Const Any Ptr ) As String
Declare Function Oct ( ByVal number As UByte, ByVal digits As Long ) As String
Declare Function Oct ( ByVal number As UShort, ByVal digits As Long ) As String
Declare Function Oct ( ByVal number As ULong, ByVal digits As Long ) As String

Parameters

NameDescription
numberA number or expression evaluating to a number. A floating-point number will be converted to a LongInt.
digitsDesired number of digits in the returned string.

Return value


A string containing the unsigned octal representation of number.

Description


Returns the unsigned octal string representation of number. Octal digits range from 0 to 7.

If you specify digits > 0, the result string will be exactly that length. It will be truncated or padded with zeros on the left, if necessary.

The length of the returned string will not be longer than the maximum number of digits required for the type of number (3 characters for Byte, 6 for Short, 11 for Long, and 22 for LongInt)

If you want to do the opposite, i.e. convert an octal string back into a number, the easiest way to do it is to prepend the string with "&O", and convert it to an integer type, using a function like CInt, similarly to a normal numeric string. E.g. CInt("&O77")

Remarks

Usage


result = Oct[$]( number [, digits ] )

Dialect Differences


  • The string type suffix "$" is required in the -lang qb dialect.
  • The string type suffix "$" is optional in the -lang fblite dialect.
  • The string type suffix "$" is ignored in the -lang fb dialect, warn only with the -w suffix compile option (or -w pedantic compile option).

Differences from QB


  • In QBASIC, there was no way to specify the number of digits returned.
  • The size of the string returned was limited to 32 bits, or 11 octal digits.

Example


Print Oct(54321)

Print Oct(54321, 4)

Print Oct(54321, 8)

will produce the output:

152061
2061
00152061
