Shuxiong Ye commented on PHOENIX-2015:
--------------------------------------
The patch above will firstly turn input to double type, and using
java.lang.Math related functions to get the result.
Note that, for both types BigDecimal and long, when type cast occurs from these
two types to double, there will be a loss of precision.
java.lang.Math is only support for double.
