[BUG] Exponentiating a zero BigDecimal by any negative long yields division by zero

[JoonasC]

Describe the bug Exponentiating a zero BigDecimal by any negative long yields division by zero.

To Reproduce Run the following code:

val a = 0.0.toBigDecimal(decimalMode = DecimalMode(6L, RoundingMode.CEILING, -1L))
val b = (-1.0).toBigDecimal(decimalMode = DecimalMode(6L, RoundingMode.CEILING, -1L))

a.pow(b.longValue(false)) // Division by zero

Expected behavior Throw a more concise exception, explaining that the negative exponentiation of zero is not defined.
