Description

while this works:
groovy> long d = 100L
groovy> d = d / 33L
groovy> d.class

Result: class java.lang.Long

the following breaks the type system and produces a Long that is a BigDecimal!

groovy> long d = 100L
groovy> d /= 33L
groovy> d.class

Result: class java.math.BigDecimal

long divided by long returns a BigDecimal in Groovy, this part is ok. What happens on the assignment is that the BigDecimal is converted into a long. This part is missing for /= it seems. So it is not a critical bug, but it is a bug
