Hyunsik Choi commented on TAJO-339:
-----------------------------------
Only double type may be enough now. Tajo needs to support auto type casting
mechanism for expressions and UDF system. sin(x:int) function will be supported
with auto type casting mechanism.
If you want to assign this issue to yourself, feel free to tell us.
> Implement sin( x ) - returns the sine of x (x is in radians)
