change decimal variable

---

Hi all,

I have one little question regarding the decimal dot of a value variable.

I have a rule which does “X = X + 0.01” (X= value of the value-variable)
My problem now is that after a few times the X is displayed with a lot of digits behind the decimal dot. (e.g. 612.5899999999995)
Over the time i will have wrong values in X.
I want to change this to always generate X with max 2 digits behind the decimal dot (612.59).

Can anyone help me to get this done ?

Thank you very much !

@s3bb0 said in change decimal variable:

X = X + 0.01

Try the following:

$X = round($X + 0.01, 2)

@mwittig cool , perfect ! thank you very much!
