Public Methods

public double asDouble ()

Returns the double representation of this NumberParts,

Throws

IllegalArgumentException	if this would lead to a loss of precision.

public long asLong ()

Returns the long representation of this NumberParts,

Throws

IllegalArgumentException	if this is not representable as a long.

public static NumberParts create (boolean negative, int exponent, long significand)

Parameters

negative
exponent
significand

public boolean equals (Object o)

Parameters

o

public int exponent ()

The actual value of the binary exponent in the floating point encoding.

public static NumberParts fromDouble (double value)

Returns the NumberParts representation of the given double.

Parameters

value

public static NumberParts fromLong (long value)

Returns the NumberParts representation of the given long.

Parameters

value

public int hashCode ()

public boolean isInfinite ()

Returns whether this NumberParts represent an infinity (positive or negative).

public boolean isNaN ()

Returns whether this NumberParts represents NaN.

There is only one NaN representation in NumberParts (unlike double).

public boolean isZero ()

Returns whether this NumberParts represents 0.

There is only one zero representation in NumberParts (unlike double, which has both negative and positive zero).

public NumberParts negate ()

Returns this NumberParts with the sign flipped.

Returns the same instance for zero (negative 0 is not representable in NumberParts) and NaN.

public boolean negative ()

True if the number was overall negative (i.e. less than zero).

public boolean representableAsDouble ()

Returns whether or not this NumberParts can be represented as a double without loss of precision.

public boolean representableAsLong ()

Returns whether or not this NumberParts can be represented as a long without loss of precision.

public long significand ()

The value of the significand in the floating point encoding, left justified, with a hidden leading one bit.
