Rounding a Field number to the nearest .5' that is pulling off of diameter

[chris_donohue5FLDZ]

I have a field setup so that it pulls the diameter of a circle & coverts it into inches, but I would like for it to be to the nearest .5". Is there a way to do that through Fields?

To do this you'll have to enter the FIELD command

Field category: select Objects

Field names: select Formula

Leave the Format as Decimal

Precision: select 0.0

In the formula window enter:

0.5*ROUND(1*12/0.5)

The 1 in this case is a place holder.

Then select 1 and right mouse click

on the cursor menu select Insert Field

Now on the 2nd FIELD window:

Field category: select Objects

Field names: select Object

Pick your Circle

Under Property select Diameter

Leave the Format as Decimal

Precision: select 0.00 <increase precision will result in higher accuracy with the rounding

Don't add the 12 factor here and click OK

Now back in the original Field window click Evaluate button and you'll see the rounded value to the nearest 0.5 in Preview:

In this example 9.77 x 12 = 117.24

The nearest 0.5 = 117.0

Here's another example with the Diameter value shown as 11.62

11.62 x 12 = 139.44

The nearest 0.5 = 139.5
