Setting precision for dimensions

[Anonymous]

Hi All,

I am actually programatically finding the arcs in the crawing and inserting the arc length as dimension. I am  able to insert, but not able to se tthe precision. I have a dimension style which is set for two decimal points. But still my arc length shows 8 digits after the decimal point.

Actual length to be shown is 179.65

Length shown in the drawing 179.65874631

How can i set the precision to 2 digits after decimal point ?
