Jose Torres created SPARK-29468:
-----------------------------------
Summary: Floating point literals produce incorrect SQL
Key: SPARK-29468
URL: https://issues.apache.org/jira/browse/SPARK-29468
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 2.4.4
Reporter: Jose Torres
A FLOAT literal 1.2345 returns SQL `CAST(1.2345 AS FLOAT)`. For very small
values this doesn't work; `CAST(1e-44 AS FLOAT)` for example doesn't parse,
because the parser tries to squeeze the numeric literal 1e-44 into a
DECIMAL(38).
