MirOS Manual: cos(3), cosf(3)

COS(3)                     BSD Programmer's Manual                      COS(3)

NAME

     cos, cosf - cosine function

LIBRARY

     libm

SYNOPSIS

     #include <math.h>

     double
     cos(double x);

     float
     cosf(float x);

DESCRIPTION

     The cos() and cosf() functions compute the cosine of x (measured in radi-
     ans). 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 C").
