Counting hits with random value. Random not working here

I'm counting hits that my object taken from towers. If this number is = 0.6 I do something.

I have action: Add random(0.3,0.6) to hited(obj. variable)

And system not gather random values. When I changed for one number "0.6" system counting properly.

Is "random(0.3,0.6)" is correct value?

From the manual:

"random(a, b)

Generate a random float between a and b, including a but not including b."

This means that:

Random(0.3 , 0.6) can be 0.3 or more than 0.3.

but it can't be 0.6. It can at most be 0.59999999 (or something like that, I don't know how precisely random operates.)

If you want a value that goes from 0.3, to and including 0.6, I recomend this expression instead:

0.3 + floor(random(31))/100.

The "Floor" expression rounds of the number downwards;

30,999->30.

0,7345->0.

25,456->25.

The /100 converts the number into the appropriate potence. (30/100=0.3)
