Feature #20705: Should "0.E-9" be a valid float value?

----------------------------------------
Ruby doesn't accept "0.E-9" as a valid float value:
```console
$ ruby -e 'Float("0.E-9")'
<internal:kernel>:218:in 'Kernel#Float': invalid value for Float(): "0.E-9" (ArgumentError)
from -e:1:in '<main>'
```
But other systems accept "0.E-9" as a valid float value:
PostgreSQL:
```text
=> select 0.E-9;
?column?
-------------
0.000000000
(1 row)
```
MySQL:
```text
> select 0.E-9;
+-------+
| 0.E-9 |
+-------+
| 0 |
+-------+
1 row in set (0.00 sec)
```
Python:
```console
$ python3 -c 'print(0.E-9)'
0.0
```
Node.js:
```console
$ nodejs -e 'console.log(0.E-9)'
0
```
Should Ruby accept "0.E-9" as a valid float value?
FYI: I don't have an opinion of this. I just realized this by an issue from an user of a maintained library by me: https://github.com/apache/arrow/issues/43877
