> BigInteger(7) / BigInteger(2) == 3
> whereas
> BigDecimal(7) / BigDecimal(2) == 4, because the result is rounded up.
> I would expect the results to be the same.
> Rather worse is:
> BigDecimal(7) % BigDecimal(2) == -1
> which makes no sense at all.
> Seems to me that the arithmetic "rules" need revisiting and rationalising - for example
why should Integer be treated as double?
> At present literal numbers are treated as Integer or Float; there's no option to generate
Long or Double literals.
