Description

In Groovy 1.8.3 the first test passes while the second fails. The return type of the second operation (and third, if it were to get to it) becomes a Double.

The tests both pass in 1.8.2.

class BigDecimalTest extends GroovyTestCase{
    public void testMath1() {
        assert BigDecimal == (3/2).getClass()
        assert BigDecimal == (7.0/8.0).getClass()
        assert BigDecimal == (new BigDecimal(3.0)/new BigDecimal(2.0)).getClass()
        true
    }

    public void testMath2() {
        assert BigDecimal == (3/2).getClass()
        assert BigDecimal == (7.0/8.0).getClass()
        assert BigDecimal == (new BigDecimal(3.0)/new BigDecimal(2.0)).getClass()
    }
}
