Why does this piece of code give 6.0000 and 5.061728 instead of 6.428571 and 5.061728? Somevar seems to be of integer type and after changing line 3 to somevar=180/280 the output is 0. What am I missing?

You have also to use floats in the calculation.

If you need to stay with the integer, you can do it like this:

Not strange. If only integers are used in a calculation, AppGameKit will only return an integer. It will not cast it to a float on it's own. Thus you need at least 1 float in the equation to return a float as Jack said.

In some languages you could do this:
somevar = (float)180 / 28

Yeah, but it involves also things like trying to round numbers with given precision (just like str(number,precision)) and many others :/

x#=123.45678
print (round(x#*100)/100)

returns 123 :/

print (Random(0,100)/100)

returns 0 and sometimes 1, while I wanted to get 2-digit random number from 0 to 1 etc.
Thanks for your answers anyway, as I said, they explain a lot.
