You might have to apporximate it using some other function. Please see ip cores in xilinx coregen module.

Depending on how much range and resolution you need, a simple look-up table stored in a block RAM may be sufficient.

That's a good idea, but can you please give me more hints or a link where i can read about this ??

Thank you,
