If you tap on an expression, then you see this. But if you set a variable to the result of this exression (1.003-1), then you will get the correct one on the display, but thewroong one when you tap on the variable. If you do get operation on this variable, you'll get the wrong result (say(my_variable)). So: what's wrong with the floating point numbers?
I started making my first multiplayer cloud game and saw this bug.
