description: Mathematical value of valid binary integer literals
info: |
    The MV of BinaryIntegerLiteral :: 0b BinaryDigits is the MV of
    BinaryDigits.
    The MV of BinaryIntegerLiteral :: 0B BinaryDigits is the MV of
    BinaryDigits.
    The MV of BinaryDigits :: BinaryDigit is the MV of BinaryDigit.
    The MV of BinaryDigits :: BinaryDigits BinaryDigit is (the MV of
    BinaryDigits × 2) plus the MV of BinaryDigit.
