Re: speed should be in double or int or float ? ?


A float should be fine. I am assuming that speed is not an integer. A double is slower and uses more memory. But there might be spots where you need the extra precision. Basically you should be economical and use the smallest that you can.

In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.
