Programming languages often have built-in routines to convert a non-negative integer for printing in different number bases. Such common number bases might include binary, Octal and Hexadecimal.



Task

Print a small range of integers in some different bases, as supported by standard routines of your programming language.



Note

This is distinct from Number base conversion as a user-defined conversion function is not asked for.)

The reverse operation is Common number base parsing.




# dec to oct
as.octmode(x)
# dec to hex
as.hexmode(x)
# oct or hex to dec
as.integer(x)
# or
as.numeric(x)
