Error description

• SKETCHER : DIMENSION CANNOT BE CORRECTLY
  ROUNDED UP WHEN ACCURACY IS SET TO 8
  DECIMAL
  .
  Scenario:
  0. Select Menu bar->Tools->Options->General-
  >Parameters and
  Measure->Units tab->Dimensions display->Display
  for the magnitude
  Length->Decimal places for read/write numbers
  and specify 3 and
  click OK.
  1. Select Menu bar->File->Open.
  2. Select Sketch.CATPart.
  3. Select Open.
  4. Select Sketch.1 and perform double click.
  5. Select 60 for dimension value and perform
  double click.
  6. Constraint Definition is displayed.
  7. Modify Value to 60.5554.
  8. Dimension value is displayed as 60.555.
  9. Select dimension value 60.555 and perform
  double click.
  10. Modify Value to 60.5555.
  11. Dimension value is displayed as 60.556.
  12. Dimension value is rounded up.
  Result A : Digit number after decimal point is 3,
  behavior of round-up and round-down follows half
  adjust rule.
  13. Select Menu bar->Tools->Options->General-
  >Parameters and Measure->Units tab->Dimensions
  display->Display for the magnitude Length-
  >Decimal places for read/write numbers and
  specify 8 and click OK.
  14. Follow from STEP1 to STEP6.
  15. Modify Value to 60.555555554.
  16. Dimension value is displayed as 60.55555555.
  17. Select dimension value 60.55555555 and
  perform double click.
  18. Modify Value to 60.555555555.
  19. Dimension value is displayed as 60.55555555.
  20. Dimension value is not rounded up. This result
  is different with result of case that Decimal places
  for read/write numbers is 3.
  Result B : Digit number after decimal point is 8,
  behavior of round-up and round-down does not
  follow half adjust rule.
  .
  Expected Result :
  Behavior of round-up and round-down should not
  depend on digit number after decimal point.It
  should be same for all allowable decimal digit.

Problem conclusion

• THIS MODIFICATION WILL BE INCLUDED IN CATIA
  DOCUMENTATION DELIVERED WITH CATIA
  VERSION 5 RELEASE 18
  .
  Existing algorithm is designed to manage round off
  value upto decimal places 8.Above this value round
  off result may be inconsistent. This behavior is
  updated in Documentation. Please refer following
  Doc reference
  Product Synthesis >>
  Knowledge Advisor>>
  Knowledge Advisor>>
  Units>>
  Magnitude Display>>
  If you specify a number of decimal places greater
  than 8 the computed value will not be rounded-up.
