The Dimension Unit Accuracy is set to round off by default on MicroStation.

for example: if the real dimension value is 6.12368, then it will be displayed as 6.1237 when Dimension Style > Unit tab > Accuracy is set to 0.1234.

but what we want is

1) round down of dimension value

dimension value will always round down to display as 6.1236 whenever the real value is 6.12361, 6.12362, ...6.12367..

2) round up of dimension value

dimension value will always round up to display as 6.1237 whenever the real value is 6.12361, 6.12362, ...6.12367..

could anyone give us some idea about this? thanks.
