0.0 is not accepted as a DoubleLiteral by the kotlin lexer.
I believe the first part of DoubleLiteral should read
: ( DecDigit+ '.'
instead of
: ( (DecDigitNoZero DecDigit*)? '.'
Reading the spec, I think 0_000.0 is also a valid DoubleLiteral which is not accepted by the lexer.
https://kotlinlang.org/docs/reference/grammar.html#DoubleLiteral
So I think the second line is also wrong.
| (DecDigitNoZero (DecDigit | '_')* DecDigit)? '.')
Maybe this instead?
| (DecDigit (DecDigit | '_')* DecDigit)? '.')
