Incompatible type 'double'

I'm assigning a CGFloat animatedDistance and I'm getting this error.

Here I'm assigning value to animatedDistance

static const CGFloat KEYBOARD_ANIMATION_DURATION = 0.3;
static const CGFloat LANDSCAPE_KEYBOARD_HEIGHT = 140;

heightFraction is CGFloat as well.

if (orientation == UIInterfaceOrientationPortrait ||
    orientation == UIInterfaceOrientationPortraitUpsideDown)
{
   animatedDistance = floor(PORTRAIT_KEYBOARD_HEIGHT * heightFraction);
}
else
{
    animatedDistance = floor(LANDSCAPE_KEYBOARD_HEIGHT * heightFraction);
}

What type should be animatedDistace? Can someone help me?

Sounds to me like you declared animatedDistance as holding some kind of pointer, such as NSNumber *, or a structure, such as CGSize. Either way, you can't assign a CGFloat there.

If animatedDistance holds an NSNumber object, create one around the value. Back when you asked this question, the way to do this was [NSNumber numberWithDouble:floor(…)]. Now, you can just use @(floor(…)).

If animatedDistance holds a CGSize or other structure, you're going to have to decide for yourself how to meaningfully convert from the single number you have to the kind of structure you want.

floor returns a double. On some platforms, CGFloat is a float. animatedDistance should be typed as a double (you can cast it to a CGFloat if needed).

Use this to get a vector... CGpoint vector = ccpSub(cgpoint 1, cgpoint 2); And if you want double/float values then do this:

CGpoint.location

for whatever you are trying to find the coordinates of, then assign a float to CGPoint.location.y and another float to CGPoint.location.x

You need cocos2d for this by the way. I think.
