PURPOSE

Convert a Recital numeric to a double


SYNONYM

api_par_nd()


SYNOPSIS

#include "dbapi.h"
 
double	_parnd(order [,index]))
 
<input parameters>
int	order;		/* Placement in actual parameter list	*/
int	index;		/* Array element index			*/
 
<output parameters>
none


DESCRIPTION

The _parnd() function returns a numeric parameter passed from Recital as a double. The order specifies the actual placement in the parameter list. If the parameter passed is an array, then the optional index value is used to specify the required element number.


EXAMPLE

The following example converts a Recital numeric value passed as the first parameter to a double.

Example Recital program:

m_double=1252
m_double =condouble(m_double)
return

Example 'C' function:

#include "dbapi.h"
 
dbapi_condouble()
{
    double	value;
 
    if ( _parinfo(1) == API_NTYPE ) {
       value = _parnd(1);
    }else {
       value = 0;
    }
 
    _retnd( value );
}
