I am really confused about float precision ..officially it's 3.4 *
(10**-38) to 3.4 * (10**+38)
But, that does not help me much even it confuse me more ....

Here is my problem:

I need to define a world of 10 000 000 units .  I need to use float for
that . I think to use only the positive part (but will depend from the
answer of my question).
What precision (after the dot ) can i expect  ?

Thanks ......
