> Please review this PR which corrects an edge case bug for
> java.text.DecimalFormat that causes incorrect parsing results for strings
> with very large exponent values.
>
> When parsing values with large exponents, if the value of the exponent
> exceeds `Integer.MAX_VALUE`, the parsed value is equal to 0. If the value of
> the exponent exceeds `Long.MAX_VALUE`, the parsed value is equal to the
> mantissa. Both results are confusing and incorrect.
>
> For example,
>
>
> NumberFormat fmt = NumberFormat.getInstance(Locale.US);
> fmt.parse(".1E2147483648"); // returns 0.0
> fmt.parse(".1E9223372036854775808"); // returns 0.1
> // For comparison
> Double.parseDouble(".1E2147483648"); // returns Infinity
> Double.parseDouble(".1E9223372036854775808"); // returns Infinity
>
>
> After this change, both parse calls return `Double.POSITIVE_INFINITY` now.
