[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).
