Since my GPU card does not support double precision, I have to use floating point instead of double. Then I encounter the following issues!
A floating point type variable’s values become integers. This variable is the result of some math calculations. I don’t understand why so because it was declared and initialized to be float point. Anything I am not aware of about cuda? Is there any way to specify the precision?
This is a general question. What’s the best way to rewrite the programs from c++ to cuda in which c++ double variables need to be converted into float point type? The straight forward way is to simply re-declare and re-initialize them from double to float point. But this caused above problem for me. any suggestions?
plz help and thanks!
