Writing an integer equivalent for the arctan() function as given in the ieee_math_real is not that difficult.

Thinking about this again, and the fact that Quartus only synthesizes real during "compile time" to generate LUTs and doesn't support varying reals during runtime, I think yes, writing an integer equivalent of arctan() would be the way to go.

Do post it up when it's ready... :) Probably they might just include it in the next revision of VHDL. ;)
