Dimension Round Up fraction retrieve API in OTK / ToolKit
Drawing contains various dimensions with different rounded up display value set by designers as below:
Dim Rounded Original
d1 154.32 154.3204
d2 150.450 150.45001
Dimension retrieve API is getting the Original value instead of display value which is rounded up.
Is there any API to retrieve rounded up value or round precision point location?
