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.
If it ain't broke, fix it until it is.
A number by itself is useful, but it is far more useful to know how accurate or certain that number is.
