I am using ruby 1.9.3
Why Integer(“09”) throws “invalid value for Integer exception” in ruby while Integer(“07”) works pretty well?
Thanks in advance.

Because a leading zero is a common convention for octal (“base 8”) notation. There is no
9digit in octal, therefore it is a syntax error to use one.If you had written
Integer("014"), you would have gotten the number 12. (Therefore, do not use leading zeroes if you do not intend the octal notation.)
