Hello!
If I do in the host code the next division with these two floats: 0.6 / 0.00001. Its result is 6000, naturally. But if I do the same operation in the device code, the result is 5999.9958.
It makes me a great colision in my program. What it’s the cause of these differents results in a simple division? What can I do to solve this problem?
I have another question: which are the functions in cuda to round a float to an int?
And I have a finally question: May I copy an array of float of 5.000.000 of positions from host to device?? In what way I should copy these array? Because I need it all in device code to process it.
I need a answer, my FPC depends on it jeje. Thanks!
I put these numbers in fixed point for clarity for all, but both of them are floats, and so it seems that cuda have a little error in divisions that it’s hard to solve, itsn’t it?
