luoyuxia updated FLINK-28234:
-----------------------------
    Description: 
When using the follwiing sql  , it will throw the 
"java.lang.NumberFormatException: Infinite or NaN"

 
{code:java}
SELECT power(-1, 0.5) {code}
It happen in ExpressionReducer, and power(-1, 0.5)  is NAN, which can't be used 
to construct BigDecimal, so the exception throws.

But for the sql,

 
{code:java}
create table src(key int);
insert into src values (-1);
SELECT power(key, 0.5) from src;{code}
 

it will run normally.

I think we  should keep same behavror for these two case, instead of throw 
exception for one case, and run normally for another case.
