str.to_i(base=10) â integer
Instance Public methods
Returns the result of interpreting leading characters in str as an
integer base base (between 2 and 36). Extraneous characters past
the end of a valid number are ignored. If there is not a valid number at
the start of str, 0 is returned. This method never
raises an exception when base is valid.
