CORDIC algorithm quickly find tangent, curvature of the output error iteration 10 < | 0.002 |, iterate 15 times the output arc error < | 0.0001 |, of the motor vector algorithm for high speed is very useful myarctan_cordic1.c input and output for the float, myarctan_cordic3.c input and output for the int, pdf file for the CORDIC algorithm works.
