A large magnitude argument may yield a result with little or no significance. For a discussion of error due to roundoff, see math(3). RETURN VALUES The cos() function returns the cosine value. SEE ALSO acos(3), asin(3), atan(3), atan2(3), cosh(3), math(3), sin(3), sinh(3), tan(3), tanh(3) STANDARDS The cos() function conforms to ANSI X3.159-1989 ("ANSI C89"). BSD May 2, 1991 BSD
