https://github.com/apache/carbondata/pull/2918 [CARBONDATA-3098] Fix for negative exponents value giving wrong results in Float datatype
Problem: When the value of exponent is a negative number then the data is incorrect due to loss of precision of Floating point values and wrong calculation of the count of decimal points.
Solution: Handled floating point precision by converting it to double and counted the decimal count values as done in double datatype(using Big Decimal).
