FCOS              Cosine (80387)              Exception Flags: I D U P S

FCOS

       Logic:      ST . cos(ST)

     FCOS replaces ST with the value of its cosine. The absolute value of ST
                    63
     must be below 2  . If it is not, C2 is set and no calculation is
     performed. If it is, C2 is set to zero, and ST is replaced with its
     cosine. ST is assumed to be in radians.
