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.
