Flexscript Coding IF Not Working

Hi, good day

I am using this code with IF but its not working properly,

I count some cummulative value and if it is still <= 1 then, it should be able to pas through an IF. But, when the value is exactly 1 it is not pass through the IF but to the else instead.

Here I attach an example of the coding I used.

The value of variable "Cek" should be 0 until all the looping. But it changes to 1 instead.

Cek Flexcript Coding.fsm

EDITED :

Sorry guys, I made the file example is wrong, the value of kumulatif should be += 1/36 and not "nilai"

Here I attached the correct file again :
cek-flexcript-coding 2.fsm

Software Version:

FlexSim 19.2.4

flexsim 19.2.4 coding

cek-flexcript-coding.fsm (23.6 KiB)

cek-flexcript-coding-2.fsm (25.0 KiB)

Your code seems to be working fine.

In every iteration where kumulatif is less than or equal to 1, the if branch executes :

Once kumulatif goes above 1, the else branch executes :

The final value of kumulatif is 18.5, which is greater than 1, so cek is 1 :

Hello, so sorry I made a mistake in the example file, please find the correct one in the second file. the value of kumulatif become 1.00000 and it goes to "ELSE" and nott "IF"

This is a floating-point precision issue (not specific to FlexSim), see this answer for more information and ways to avoid it : Incorrect calculation values - FlexSim Community

I see, but In the output windows, the precision unit of the variable kumulatif is 1.00000000 is not it the same as 1 or the output windows is not showing all the decimal precision in Flexsim ? because I tried to changes the if criteria 1 to 1.00000000 and it is still not working.

But anyways, in the end I am changing the IF criteria to " kumulatif <= 1.000000000001" It solve this one example.

Thank you

@Ranggi M You might want to check your calculation. The first value is for kumulatif and second value is cek. after a few loop, kumulatif is more than 1.
