Field Detail

DIVIDE_GENERIC

public static final int DIVIDE_GENERIC

Implement's Scheme / operation.

Constant Field Values

DIVIDE_INEXACT

public static final int DIVIDE_INEXACT

Implements a division operation. Like Scheme's (exact->inexact (/ x y)).

See Also:

Constant Field Values

QUOTIENT

public static final int QUOTIENT

Implements a quotient operation. Depends on the value of getRoundingMode(). Operands are real; result is an integer. Inexact operands yield inexact integer result.

Constant Field Values

QUOTIENT_EXACT

public static final int QUOTIENT_EXACT

Implements a quotient operation. Depends on the value of getRoundingMode(). Operands and result are real. Operands are real; result is an integer. Inexact operands yield exact integer result.

Constant Field Values

MODULO

public static final int MODULO

Implements a modulo/remainder operation. Depends on the value of getRoundingMode(). Operands and result are real.

               int op)

Method Detail

defaultResult

public java.lang.Object defaultResult()

isSideEffectFree

public boolean isSideEffectFree()

Description copied from class: Procedure

True if this Procedure (definitely) has no side-effects. Note side-effect-free does not imply idempotent if this allocates an object with "identity".

Overrides:
