Looking for IPs from XILINX fp_add

[Zerox100]

Dear my friends,

I have found a verilog code from this link. But some modules is missing. for example "fp_add". I guess it is a prebuild xilinx ip core. I have two questions.

Am i right?
I cant find the description of this module. Vivado cant specify it. why

Why do you think that's a Xilinx IP? There's nothing you've posted to indicate that. Where is that code from?

You can compile the design and see for yourself (provided you have added to the design all the required sub-modules)!
