So I need to change the precision on just one custom property value.

Let's say the CP "Length" is entered with 4 decimal places 8.0000

I do some math in the equation manager and want to output a value with 4 decimal places, say 16.0000, but SW outputs just 16

How can I get the value to output correctly?

I know ROUND() can get you less decimals when you have too many.

Is there a way to make this work the other way?

I guess I need trailing zeros in equations? Is there an option for that?

Trailing zeroes in equations are impossible to get. It is a current limitation.

No matter what precision you have, no matter what rounding you use, trailing zeroes are impossible in the equations area (global variables, etc...)

Every where else they work.....not there.

I have an ER for this....I will post it as soon as I find it
