cos(3F) cos(3F)
NAME
cos, dcos, ccos - FORTRAN cosine intrinsic function
SYNOPSIS
real r1, r2
double precision dp1, dp2
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
returns 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
argument.
