thanks sunji!
Those both help quite a lot because I was sending values off some photo resistors into an Arduino, and then to PD with Pduino, and then to Flash with flashserver, and the numbers were to tell a movie clip in flash to go to and play whatever number is coming through, but because they were numbers with decimals Flash couldn't figure out which frame to play since it wasn't a whole number.
The [int] fixed that perfectly and I will try out the rounding action later when I get back home.
Everything is working great and I'm freaking out on how fun it is! Hooray Pd
