    text/scanner: don't allow Float exponents with no mantissa · 6c7e199e
    Ben Hoyt authored
    Previously Scanner would allow float literals like "1.5e" and "1e+"
    that weren't actually valid Go float literals, and also not valid
    when passed to ParseFloat. This commit fixes that behaviour to match
    the documentation ("recognizes all literals as defined by the Go
    language specification"), and Scanner emits an error in these cases.
    
    Fixes #26374
