A integer in ruby is a numeric value, it's not octal or decimal.

A string representation of a number can be octal or decimal or whatever.
The Ruby as well and the C library have means to convert between numbers
and its string representations.

num = "775".to_i(8)
dec = num.to_s             #> "509"
oct = num.to_s(8)          #> "775"
