如何以orc格式存储十进制值？

Question

Orc format defines double and float . Is there a way to store BigDecimal value with scala and precision attributes?

Answer 1

From API specification:

public final class MathContext

Immutable objects which encapsulate the context settings which describe certain rules for numerical operators, such as those implemented by the BigDecimal class. The base-independent settings are:

precision: the number of digits to be used for an operation; results are rounded to this precision roundingMode: a RoundingMode object which specifies the algorithm to be used for rounding.
