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.
