CSPICE_RPD returns the double precision value of the constant PI/180
which represents the number of radians per degree of arc.
For important details concerning this module's function, please refer to
the CSPICE routine rpd_c.
No input required.
radians_per_degree = cspice_rpd()
A double precision scalar, the number of radians per
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.
IDL outputs: 0.017453293
The IDL system variable !DTOR returns a single precision (float) value
for PI/180 that equates to the value returned by the expression
float( cspice_rpd() ).
