description: Mathematical value of valid binary integer literals
info: |
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 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.
