Decimal Precision - 1/16" accuracy in model

I’m importing values from excel and I’d to set up some geometry that is accurate to the 1/16". However, Dynamo is rounding my floating numbers and not creating the geometry to the accuracy I need. How do I solve this?

Not sure if this is the issue, but have you checked the Number Format settings

Dynamo doesn’t round values, only their visual representation on canvas. Are you sure that the rounding doesn’t happen before you import the values?
