Need help with this error!! < INT_MIN || f > INT_MAX

When I try to make a new terrain it gives me this error as shown below:

f < INT_MIN || f > INT_MAX

Please help so I can get on with “attempting” to create a game.
I only got Unity 3D today!

Are You sure this only happens in your terrain? Because i also have this problem, but it occurs on my crosshair script.
