cos(3F) cos(3F)NAME cos, dcos, ccos - Fortran cosine intrinsic function SYNOPSIS real r1, r2 double precision dp1, dp2 complex cx1, fx2 r2=cos(r1) dp2=dcos(dp1) dp2=cos(dp1) cx2=ccos(cx1) cx2=cos(cx1) DESCRIPTION cos returns the real cosine of its real argument. dcos re- turns the double-precision cosine of its double-precision argument. ccos returns the complex cosine of its complex argument. The generic form cos may be used with impunity because its returned type is determined by that of its argu- ment. SEE ALSO trig(3M). April, 1990 1
