SYNOPSIS

elemental real function acosd(value)
    class(*),intent(in) :: value

DESCRIPTION

Calculate arcsine of input value in degrees. It converts the input value from degrees to radians and calls acos(3f).

OPTIONS

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

EXAMPLE

Sample program

   program demo_acosd
   use M_units, only :  acosd, cosd
   implicit none
      write(*, *)       cosd(0.0),cosd(45.0),cosd(120.0),cosd(180.0),cosd(720.0)
      write(*, *)acosd([cosd(0.0),cosd(45.0),cosd(120.0),cosd(180.0),cosd(720.0) ])
   end program demo_acosd
