Procedure.executehf - execute a Maple procedure using hardware floats
Calling Sequence
double executehf( ) throws MapleException
double executehf( double args[] ) throws MapleException
Parameters
args
-
array of doubles to be used as arguments to the procedure
Description
The executehf function executes the procedure represented by the Procedure object with the given arguments using hardware floats.
Not all procedures can be executed using hardware floating-point. For information on the restrictions on functions evaluating using the hardware floating-point system, see evalhf/procedure. For more information on the Maple hardware floating-point evaluation system, see evalhf.
Examples
import com.maplesoft.openmaple.*;
import com.maplesoft.externalcall.MapleException;
class Example
{
public static void main( String notused[] ) throws MapleException
String mapleArgs[];
Engine engine;
Procedure p;
double args[];
mapleArgs = new String[1];
mapleArgs[0] = "java";
engine = new Engine( mapleArgs, new EngineCallBacksDefault(),
null, null );
p = (Procedure)engine.evaluate( "proc( ) return Pi; end proc:" );
System.out.println( p.execute() );
System.out.println( p.executehf() );
p = (Procedure)engine.evaluate( "proc( x,y,z ) return (x+y)/z; end proc:" );
args = new double[3];
args[0] = 100;
args[1] = 900;
args[2] = 15.0;
System.out.println( p.executehf( args ) );
p = (Procedure)engine.evaluate( "proc( x ) return sin(Pi*x); end proc:" );
args = new double[1];
args[0] = 1000;
}
Executing this code produces the following output.
Pi
3.141592653589793
66.66666666666667
-3.214166459275633E-13
