Issue:

Wrong result of the Round function in Inventor Parameter window.

The two numeric user parameters are created:

  • with a unit (mm): x = 128.5 mm
  • unitless (ul): y = round(x)/1mm 

The value of the y parameter is wrong (130 instead of 129).

 

wrong result of the round function in parameter window

Causes:

The round function requires a unitless parameter as an argument. The argument x is not unitless.

Solution:

Use a unitless argument for the round function. Instead of:

y = round(x)/1mm 

use:

y = round(x / 1 mm)

correct result of the round function in parameter window
