Hi there,

I've found following issue with bigDecimalOf code:

    @Test
    fun typeCastIssue() {
        val zero = BigDecimal.ZERO
        println(zero == Decimal.NEGATIVE_ZERO) // true
        bigDecimalOf(zero) // throw exception
    }

Seems like the when condition here is an equivalence test, not asserting same object. So if num = BigDecimal.ZERO, then it enters this branch and fail type cast.

Could you take a look? Thanks!
