Detection of NaN in IPPS functions

255 Views

I'm doing a division on some 32f values that could have zeros in both operands. This will result in a NaN. Now, I'd like to change all the NaNs to zeros, but I don't see how to do it without an not equal function or a NaN-specific function.

I'm using IPP 5.0, but I can upgrade if necessary.

Thanks!
