--------------------------------------
Hi Josh,
Can you tell me why in the UDFRound.java, the math context is being initialized
with the formula bd.precision() - (bd.scale() - i.get())? This is causing some
issues with respect to calls such as round(55555, -6) etc. The reason is the
bigdecimal constructor sets precision by default to the number of digits of the
integer passed into it. In this case for 55555, it is set to 5 and the scale by
default is 0. This implies that for this case, the formula above results in a
negative number that the mathcontext constructor cannot take. I am not sure
what the behavior should be?
Thanks
Vikram.
