BigDecimalParseSettings

final case class BigDecimalParseSettings(mathContext: MathContext = MathContext.DECIMAL128, scaleLimit: Int, digitsLimit: Int) extends Product with Serializable

Parse settings for BigDecimals. Defines limits that will be used when parsing the BigDecimals, like how many digits are accepted.

mathContext: the MathContext used when parsing.
scaleLimit: limit the scale, and it is related to the math context used.
digitsLimit: how many digits are accepted, also related to the math context used.
