In what al language can the algorithm for converting decimal numbers to octal be represented?

Question

Programming

There is no algorithmic language that can use both decimal and octal numbers.

Answer 1

There are no decimal and octal numbers.
There are numbers, but there is their notation - binary, octal, decimal, hexadecimal...
The number is the same, but the line of text representing it is different.

Answer 2

In C it is possible - 0123 = 123 ₈ . But why do you need it?
Usually a number in any positional number system - 10th, 8th, 16th - is written in a line. And I don’t say “transfer from the 10th system to the 8th”, but “transfer from the native system to the octal system” - because it doesn’t matter which system is native, the main thing is that we can perform arithmetic operations in it.
