floor isn't quite the same as round, e.g. floor( 0.9 ) != round( 0.9 ). You
can use floor to simulate round
float round( float x )
return floor( x+0.5 );

It's just a question of figuring out the average number of tomatoes you need
in each gap and then dealing with the problem that you can't actually slice
them up. There's nothing in there that I would call deep math. All the fancy
crypto stuff loses me in no time flat.
