having a problem with "greater than"

I made an event to subtruct 0.1 from a certian variable as long as this variable is > 0, but every time it reaches 0 it does it another time and then stops (so it reaches -0.1).

can some plaese tell me why this happans?

It's going to be some other part of your code causing this. Would have to see the code to offer suggestions.

ok, how can I paste here an image?

Many users forget that computer precision is not always what they expect. So for instance, if you are checking for a value to exactly equal another, due to computer float rounding errors, this may never occur.

Without seeing the events it's impossible to say, but ensure that you have taken account of the precision errors that may occur - i.e. don't check for an exact value if possible.

so ins't any way to fix it?

Would need to see what you've done. Generally, use such things as INT, FLOOR, ROUND, CEILING etc to ensure that fractional parts don't come into it.

ok thanks
