Scale can cause unitiuitve negative decimal precision error

[Snipesy]

Using the scale method on a BigDecimal can throw the "Negative decimal precision is not allowed." exception even if the new scale satisfies that condition.

 val b = BigDecimal.fromDouble(
    0.05,
    decimalMode = DecimalMode(
        decimalPrecision = 5,
        roundingMode = RoundingMode.ROUND_HALF_FLOOR,
        scale = 6
    )
)
val c = b.scale(2) // <- Throws here?

Thanks for reporting, using precision together with scale should error out immediately, we'll look into this.
