### Is your feature request related to a problem or challenge?
DataFusion supports casting the string `4e7` to float but not to decimal.
This is inconsistent with Postgres (and Apache Spark).
## Postgres
```
postgres=# select cast('4e7' as float);
float8
----------
40000000
(1 row)
postgres=# select cast('4e7' as decimal(10,2));
numeric
-------------
40000000.00
```
## DataFusion
```
DataFusion CLI v37.0.0
❯ select cast('4e7' as float);
+-------------+
| Utf8("4e7") |
+-------------+
| 40000000.0 |
+-------------+
1 row in set. Query took 0.010 seconds.
❯ select cast('4e7' as decimal(10,2));
Arrow error: Cast error: Cannot cast string '4e7' to value of Decimal128(38,
10) type
```
