DESCRIPTION

The _parni() function returns a numeric parameter as an integer. 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 numeric value passed as the first parameter to an integer.

Example Lianja script:

m_int=1252
m_double =conint(m_int)
return

Example 'C' function:

#include "lianja_api.h"
 
lianjaapi_conint()
{
    int	value;
 
    if (_parinfo(1) == API_NTYPE) {
       value = _parni(1);
    }else {
       value = 0;
    }
 
    _retni( value );
}
