    20.1.1.1 Number ( [ value ] )

    When Number is called with argument number, the following steps are taken:

    1. If no arguments were passed to this function invocation, let n be +0.
    2. Else, let n be ToNumber(value).

    [...]

    7.1.3.1 ToNumber Applied to the String Type

    All grammar symbols not explicitly defined above have the definitions used
    in the Lexical Grammar for numeric literals (11.8.3)

    [...]

    The MV of OctalIntegerLiteral :: 0o OctalDigits is the MV of OctalDigits.
    The MV of OctalIntegerLiteral :: 0O OctalDigits is the MV of OctalDigits.
    The MV of OctalDigits :: OctalDigit is the MV of OctalDigit.
    The MV of OctalDigits :: OctalDigits OctalDigit is (the MV of OctalDigits ×
    8) plus the MV of OctalDigit.
