This is correctly IMHO a "trailing uc" error.

But -9_.8 is ok so the problem is with having a leading
underscore?! Are we misunderstanding each other? Please check again:

$ irb
irb(main):001:0> -9_.8
-9.8
irb(main):002:0> -9_._8
SyntaxError: compile error
(irb):2: trailing `_' in number
-9_._8
   ^
        from (irb):2
