I am using Inventor 2012. I am trying to use the Round fuction in a parameter with no luck.
I have a the following parameters
wire_offset in wire_space+wire_wdt 0.231186
wire_offset_round ul round(wire_offset/1 in) 1.000
When I do wire_offset_round like this it works. But if I want it to a 3 place decimal it does not work
wire_offset_round ul round((wire_offset/1 in), 3 ul)
According to the Inventor help, I should be able to do this. But I can't. I even tried it without the ul after the 3 and nothing. Any clues?
I am not sure which help you read, but, NO it will not work.
round (expr) will round to the closest whole number.
The syntax you have used WILL work with iLogic, and will change the rounding of an exported parameter, found in "iProperties, Custom"
What you can do for your current issue is change the precision of the value.
- RMB on "wire_offset"
- select "Custom property format"
- Change "precision" to 3
This will change the display of the value but not the value its self.
I will try and find the syntax to change the value, I have used it, but it does not always go in the direction you want it to. (Floor and ceil)
In your example, I'm not clear how .231186 rounds to 1.000? Doesn't work that way for me in 2013, anyway. If, as I suspect, you want the number rounded to three decimal places, then the following should work:
wire_offset_round ul round(wire_offset * 1000 ul / 1 in) / 1000 .231000
