JavaScript number literals
Should match any valid JavaScript number literal.
Allow _ as a numerical separator, leading/trailing dot and 0, and test for prefix 0b (binary), 0o (octal), and 0x (hexadecimal).
See the second paragraph of EDIT 4 in this StackOverflow answer by me for matching JS numbers.
