Variable I/O Description
-------- --- --------------------------------------------------
n I The number of double precision values to compare.
... I The numbers to be compared, separated by commas.
- Detailed_Input
n is the number of double precision values in the set
whose maximum is to be determined.
... represents a variable argument list. The number of
double precision values supplied must be that
indicated by n. The values are separated by commas.
Section 5.2.4.1 of the ANSI C Standard, titled
"Translation Limits," specifies that argument lists
containing at least 31 items must be supported. In
the interest of portability, no more than 30
double precision values should be supplied.
- Detailed_Output
The function returns the maximum of the set of input double precision
values.
- Parameters
None.
- Examples
1) Find the maximum of four double precision values.
#include "SpiceUsr.h"
.
.
.
SpiceDouble max;
SpiceDouble a;
SpiceDouble b;
SpiceDouble c;
SpiceDouble d;
.
.
.
max = maxd_c ( 4, a, b, c, d );
- Restrictions
1) The ANSI C Standard specifies that argument lists containing 31
actual arguments must be supported. Larger sets of values may
not be handled properly by this routine.
- Exceptions
Error free.
1) If n is less than 1, the value 0.0 is returned.
2) If the number of double precision values supplied does not match
the argument n, the action of this routine is not defined.
3) If the number of double precision values supplied exceeds 30,
the action of this routine is not defined.
- Files
