-* This is a faster version of the BLAS1 routine ZROTG, except for
-* the following differences:
-* F and G are unchanged on return.
-* If G=0, then CS=1 and SN=0.
-* If F=0, then CS=0 and SN is chosen so that R is real.
-*
-* Arguments
-* =========
-*
-* F (input) COMPLEX*16
-* The first component of vector to be rotated.
-*
-* G (input) COMPLEX*16

-*
-* CS (output) DOUBLE PRECISION
-* The cosine of the rotation.
-*
-* SN (output) COMPLEX*16
-* The sine of the rotation.
-*
-* R (output) COMPLEX*16
-* The nonzero component of the rotated vector.
