0.1 being changed to 0.0 with default settings

[mgroth0]

I need a little help understanding this library. My current understanding is that the default settings have unlimited precision. However, this code fails:

var bignum = 0.1.toBigDecimal(decimalMode = DecimalMode.DEFAULT)
bignum *= 2
bignum.doubleValue(exactRequired = false) shouldBe 0.2

io.kotest.assertions.AssertionFailedError: expected:<0.2> but was:<0.0>
