Hello!
(if this isnt the right place to post a question like this, please let me
know.. cheers)..

Pretty new to java am i, experience is limited to designing an animated
button for myself so far, my new project is an an applet which moves points
around the screen at varying speeds and accelerations...(the speed of a
point needs to have decimal points in my applet otherwise the result isnt
smooth, and no small diferentiations between speeds can be made. Am i
missing something and is there some kind of class that does this kind of
thing for me??)

Questions:

a number with a decimal point is called a float ( is this true?? )

images can only be printed at 'int' coordinates ( is this true?? )

how would i convert a float to the nearest int so that i can print the
bugger to screen.
