public PrimIEEE64(double value)

PrimIEEE64

public PrimIEEE64(Rcvr receiver)

Method Detail

actualHashForEqual

public int actualHashForEqual()

Overrides:

actualHashForEqual in class Heaper

isEqual

public boolean isEqual(Heaper other)

Description copied from class: Heaper

Return true if the two objects are equal.

Overrides:

isEqual in class Heaper

asIEEE128

public IEEE128 asIEEE128()

Description copied from class: PrimFloatValue

The value as an IEEE 128-bit floating point number.
May not be possible if conversion from subclass to IEEE type is not available.

Overrides:

asIEEE128 in class PrimFloatValue

asIEEE32

public float asIEEE32()

The value as an IEEE 32-bit floating point number

Overrides:

asIEEE32 in class PrimFloatValue

asIEEE64

public double asIEEE64()

The value as an IEEE 64-bit floating point number

Overrides:

asIEEE64 in class PrimFloatValue

bitCount

public int bitCount()

Description copied from class: PrimFloatValue

What precision is it, in terms of the number of bits used to represent it. In the
interests of efficiency, this may return a number larger than that *needed* to represent
it. However, the precision reported must be at least that needed to represent this
number. It is assumed that the format of the number satisfies the IEEE radix independent
floating point spec. Should we represent real numbers other that those representable in
IEEE, the meaning of this message will be more fully specified.
The fact that this message is allowed to overestimate precision doesn't interfere with
equality: a->isEqual(b) exactly when they represent that same real number, even if one of
them happens to overestimate precision more that the other.

Overrides:

bitCount in class PrimFloatValue

exponent

public IntegerVar exponent()

If this is a number, return the exponent

Overrides:

exponent in class PrimFloatValue

isANumber

public boolean isANumber()

Description copied from class: PrimFloatValue

Return TRUE if value represents a number.

Overrides:

isANumber in class PrimFloatValue

mantissa

public IntegerVar mantissa()

Description copied from class: PrimFloatValue

If this is a number, return the signed mantissa

Overrides:

mantissa in class PrimFloatValue

sendSelfTo

public void sendSelfTo(Xmtr xmtr)

Description copied from class: Heaper

do nothing

Overrides:

sendSelfTo in class PrimFloatValue

make

public static Heaper make(double value)
