changing default rounding mode from ROUND_HALF_EVEN to ROUND_HALF_UP

[Si Chen]

Hey everybody,

You may have seen the email from Leon Torres earlier about rounding.   
I think we should change the arithmetic settings to ROUND_HALF_UP  
from ROUND_HALF_EVEN, for the following reason:

0.825 ROUND_HALF_UP: 0.83
0.824 ROUND_HALF_UP: 0.82
0.825 ROUND_HALF_EVEN: 0.82
0.824 ROUND_HALF_EVEN: 0.82

This would involve modifying the arithmetic.properties file and then  
taking a look at the Calculate operation in minilang and its default  
rounding mode.
