oct

oct(n, [pad])

Convert an integer to an octal string, optionally specifying a number of digits to pad to.

Examples

In the Julia programming language, the function oct(n, [pad]) is used to convert an integer n to its octal representation as a string. Optionally, you can specify the number of digits to pad the resulting octal string.

1. Convert an integer to an octal string:

   julia> oct(10)
   "12"
   
   julia> oct(15)
   "17"

   The oct function converts the integer n to its octal representation as a string.

2. Specify the number of digits to pad:

   julia> oct(10, 4)
   "0012"
   
   julia> oct(15, 6)
   "000017"

   By specifying the pad argument, the resulting octal string is padded with leading zeros to match the specified number of digits.

Common mistake example:

julia> oct(-10)
ERROR: DomainError with -10:
-10 is not a non-negative integer.

In this example, the oct function expects a non-negative integer as the argument. Providing a negative integer will result in a DomainError. Ensure that the input is a non-negative integer when using the oct function.
