Parameter value has to take next even number

[Anonymous]

Hello Folks 

I have bush having parameter called OD ,  this OD has some expression and the value of this OD=21.366 like this 

I want a code to bias this OD value to next even nuber 

I mean code has to automate the value to next even nuber , above said example  OD=22 

Please help me out

Kiran, when you create a new Userparamter with this equation you get the next rounded number:

ceil(OD / 1 mm) * 1 mm - where OD=21.366 is the name of your parameter gives your 22 mm (rounds to the ceiling)

floor(OD /1 mm) * 1mm gives you 21 mm (rounds to the floor) and

round (OD / 1mm) * 1mm gives you the nearest rounded value.

when you use floor(OD / 2 mm) * 2 mm you get the rounded even number 20mm.

Hello Rob

In this above shown bush design ,  my Inventory shop always have even number Small_OD bushe sizes 

Please give me iLogic code to make Small_OD value always should be even number of next increment 

Small_Dia=15.46

Small_OD=Small_Dia+6=21.46

But i want iLogic code to make this 21.46 values should be next even number say 22

Please help me out

Why do you want to use iLogic for this task? And where do you get the Small_Dia value from?

It's posible to directly use the ceil, round, floor options within a dimension, see screenshot. Please have a good look at the space used in the formula otherwise it's not working.

When you want to use iLogic: in the Math section of the snippets there are also the ceil, round and floor functions explaned.

You can use this :

Create 3 user parameters in Inventor : val, test, final_val, all in cm, where val is the original value, test is an intermediate test value and final_val is the result

test = round(ceil(val) / 2 nd) - floor(val / 2 nd)

final_val = ( floor(val / 2 nd) + test ) * 2 nd

Result obtained :

val = 5 --> final_val = 6

val = 5.3 --> final_val = 6

val = 8 -->  final_val = 8

val = 8.2->  final_val = 10

Hope this help !

Alain, you made a complicated formula. What is the benefit of this way compaired to the option i gave?

And there are some errors in your formula's because of a unit type mismatch, see also the red color in the parameter screen. You use the non existing "nd" unit.

Effectively, I misundesrtood your answer with the drawing...

For the red color in the formula, it's because Inventor use nd by default, I have not replaced with mm.

So your answer is the simple way, mine is the secret one ^^.

many Thanks rob , it worked.

In this below image, I want to make highlighted parameter in to roundfigure.  please provide me the similar kind of code

Use isolate Function

for unit replace
