SYNOPSIS

elemental real function cosd(degrees)
     class(*),intent(in) :: degrees

DESCRIPTION

Calculate cosine of input value in degrees

OPTIONS

degrees
any standard scalar value supported by anyscalar_to_double(3f).

EXAMPLE

Sample program

   program demo_cosd
   use M_units, only :  cosd
   implicit none
      write(*,*)’With REAL array input    ’, &
      & cosd([ 0.0, 15.0, 30.0, 45.0, 60.0, 75.0, 90.0, 180.0, 270.0 ])
      write(*,*)’With INTEGER array input ’,  &
      & cosd([0,15,30,45,60,75,90,180,270])
      write(*,*)’With DOUBLEPRECISION     ’,        &
      & cosd(0.0d0),cosd(15.0d0),cosd(90.0/3.0d0),  &
      & cosd(90.0/2.0d0),cosd(60.0d0),cosd(75.0d0), &
      & cosd(90.0d0),cosd(180.0d0),cosd(270.0d0)
   end program demo_cosd
