Method Detail

asIEEE128

public IEEE128 asIEEE128()

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

asIEEE32

public float asIEEE32()

The value as an IEEE 32-bit floating point number.
May not be possible if conversion from subclass to IEEE type is not available.

asIEEE64

public double asIEEE64()

The value as an IEEE 64-bit floating point number.
May not be possible if conversion from subclass to IEEE type is not available.

bitCount

public int bitCount()

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.

exponent

public IntegerVar exponent()

If this is a number, return the exponent

isANumber

public boolean isANumber()

Return TRUE if value represents a number.

mantissa

public IntegerVar mantissa()

If this is a number, return the signed mantissa

isNumber

public boolean isNumber()

precision

public int precision()

sendSelfTo

public void sendSelfTo(Xmtr xmtr)

Description copied from class: Heaper
