Problem about parameter

[LEE MENG CHE]

Hi

There is a problem in IronCAD parameter , it's seems a bug.

Please see this parameter D2 , the expression is IF((WSpace<=300mm),((0-DALHeight)/2),-0.049) , I set Width = 400 , so the WSpace = 300 , D2 should be (0-399)/2=-199.5 , but the result is -49 , the formula "<=" doesn't worked .

 

TEST(1).ics

Note from R&D:

It is computer tolerance issue.   Can they try to use 300.0000001 as workaround.  
I think we should fix it in the next release.

Probably floating point tolerance issue?

Good job Lee

That's an interesting thing I found , if the WSpace no Expression , D2 will correct .

IronCAD does not allow 0.0000001 to input in expression

But 0.00001 or 0.01 also working correctly

Hi Kim 

I think that is make sense , actually 300.001 mm <= 300 , so D2 will be -199.5 , like cheating the parameters system.

Hope it be fixed in next version.

This issue should be fixed in version 2023.

@LEE you can also use INT function for round value.

As you see working...
