Abstract

   CSPICE_J1950 returns the value for the Julian Date of
   1950 JAN 01 00:00:00 (1950 JAN 1.0).

I/O

   Given:

      No input required.

   the call:

      j1950 = cspice_j1950

   returns:

      j1950   the value 2433282.5, the Julian Date corresponding to
              1950 JAN 01 00:00:00 (1950 JAN 1.0).

              [1,1] = size(j1950); double = class(j1950)

Parameters

   None.

Examples

   Any numerical results shown for this example may differ between
   platforms as the results depend on the SPICE kernels used as input
   and the machine specific arithmetic implementation.

   1) Display the double precision value for the J1950 date.

      Example code begins here.


      function j1950_ex1()
         %
         % Display the J1950 date in 16.8 format
         %
         fprintf( 'J1950 date: %16.8f\n', cspice_j1950)


      When this program was executed on a Mac/Intel/Octave6.x/64-bit
      platform, the output was:


      J1950 date: 2433282.50000000
