Rounding Mode

As many Intel IPP functions have to meet the bit-exact requirement, image processing functions use rounding. The default rounding mode for all functions can be described as "nearest even", that is the fixed point number x=N + α, 0 ≤ α < 0, where N is an integer number, is rounded as given by:

Removed Functions

This appendix contains the table that lists the Cryptography functions removed from Intel IPP 9.0. If an application created with the previous versions calls a function listed here, then the source code must be modified. The table also specifies the corresponding Intel IPP 9.0 functions or workaround to replace the removed functions.


Computes the exponential of pixel values in a source image and writes the results into the destination image.
