Description

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.
