CSPICE_B1950 returns the double precision value of the Julian Date
corresponding to Besselian Date 1950.0: 2433282.42345905.
Given:
None.
the call:
b1950 = cspice_b1950( )
returns:
b1950 2433282.42345905, the Julian Date corresponding to Besselian
Date 1950.0.
help, b1950
DOUBLE = Scalar
None.
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 Julian Date
corresponding to the Besselian date 1950.0.

-Icy Version 1.1.1, 31-MAY-2021 (JDR)
Edited the header to comply with NAIF standard.
Added -Parameters, -Exceptions, -Files, -Restrictions,
-Literature_References and -Author_and_Institution sections, and
completed -Particulars section.
Removed reference to the routine's corresponding CSPICE header from
-Abstract section.
Added argument's type and size information in the -I/O section.
-Icy Version 1.1.0, 06-SEP-2005 (EDW)
Update to header reflecting edits made to b1950_c.c.
That call now returns 2433282.42345905, instead of
2433282.4234 (the previous return value).
-Icy Version 1.0.0, 16-JUN-2003 (EDW)
besselian date 1950.0
