Method Details

getRoundingMode

public int getRoundingMode()

Return one of FLOOR, CEILING, TRUNCATE, ROUND, or 0 if not applicable. These are defined in gnu.math.Numeric.

applyN

public Object applyN(Object[] args)
              throws Throwable

Overrides:

applyN in class Procedure

Throws:

Throwable

apply2

public Object apply2(Object arg1,
 Object arg2)
              throws Throwable

Overrides:

apply2 in class Procedure

Throws:

Throwable

numArgs

public int numArgs()

Description copied from class: Procedure

Return minArgs()|(maxArgs<<12). We use a single virtual function to reduce the number of methods in the system, as well as the number of virtual method table entries. We shift by 12 so the number can normally be represented using a sipush instruction, without requiring a constant pool entry.

Overrides:

numArgs in class Procedure
