Oct
 
Converts a number to octal representation

Syntax
Usage

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

Parameters

number
A number or expression evaluating to a number. A floating-point number will be converted to a LongInt.
digits
Desired 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 using ValInt or ValLng, similarly to a normal numeric string. E.g. ValInt("&O77")

Example

Print Oct(54321)
Print Oct(54321, 4)
Print Oct(54321, 8)

will produce the output:

152061
2061
00152061

Dialect Differences

  • The string type suffix "$" is obligatory in the -lang qb dialect.
  • The string type suffix "$" is optional in the -lang fblite and -lang fb dialects.

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.
