> 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.
