# [DRILL-8066](https://issues.apache.org/jira/browse/DRILL-8066): Convert
non-finite floating point literals to string RexLiterals
## Description
When we encounter floating point literals in a query we attempt to convert
them to BigDecimal which can only handle finite floats. making queries like
this fail: `select cast('-Infinity' as float);`. This change sends non-finite
floats to Strings.
## Documentation
None.
## Testing
New unit test: TestMathFunctionsWithNanInf#testNanInfLiteralConversion
Manually run `select cast('-Infinity' as float);`

> Drill can process floating point values like -Infinity, +Infinity and NaN but
> it fails to correctly convert queries containing these values as constants
> during planning. E.g. this query produces a NumberFormatException.
