Improve double precision
-------------------------
Key: PIG-2406
URL: https://issues.apache.org/jira/browse/PIG-2406
Project: Pig
Issue Type: New Feature
Reporter: Anitha Raju
Hi,
When 2.51 (type: double) is added 24 times using SUM, it gives you result of
60.23999999999997.
If a user wants to control the precision, that is, in the result he requires
60.24, it wouldnt be possible unless he implements a custom UDF.
So if we can have a way to improve double precision,
for eg: http://docs.oracle.com/javase/1.5.0/docs/api/java/math/BigDecimal.html
Here with BigDecimal, one can improve the double precision and with
MathContext, the user has control to set the precision.
Can we have a new UDF which can do the same?
Regards,
Anitha
