cannonball game problem

[Sevensins]

ok for my grade 11 project I need to create a simple cannonball game where you enter the velocity and angle. My teacher gave me the formula but she went to a confrence for a week and the sub. cant help me so i need help. The formula goes somthing like this
"x:= round(5*velocity*time*cosd(angle))"
"y:=round(5*velocity*time*sind(angle)*0.5*time*time)"
i know about the predefined words its just that it says "interger overflow in 'round' on y's line.
can anyone figure it out

It would help to see all of the code, but it's my bet that that time^3 you have going on there isn't helping you much....
Can't really do too much until we can figure out what sort of values you are dealing with.

Well a few months ago I wanted to make the same thing as you, but gave up . Anyways, this is what I came up with. I know its not quite correct but maybe it will point you in the right direction...

Turing:

const GRAVITY := -0.0001 var x, y, xSpeed, ySpeed, angle,power : real := 0 put "Angle: " get angle put "Power: " get power xSpeed := cosd(power)/5 ySpeed := sind(angle)/5 loop setscreen("offscreenonly") View.Update     x += xSpeed     y += ySpeed     ySpeed += GRAVITY     Draw.FillBox(0,0,maxx,maxy,white)     Draw.FillOval (round (x), round (y), 3, 3, black) end loop
