Round truncated amounts down instead of up

[nahuhh]

1.23456 should round to 1.2345.

Rounding up to 1.2346 makes users think they have more than they really do

or forego rounding and just drop the trailing #s

UW cannot show an unrealistic balance.
Truncated and stop. Neither up nor down.

Agreed.
