Enclosing class:

RealRepresentation

private static final class RealRepresentation.DoubleRep
extends RealRepresentation

Describes the representation of a double, resp. a Double-value. It is characterized by the RealRepresentation.mantissa() and the RealRepresentation.exponent. The mantissa in turn splits into the RealRepresentation.integer and the RealRepresentation.fractional part.

Constructor Detail

DoubleRep

DoubleRep(double dbl)

Constructs a newly allocated DoubleRep object that represents the primitive double argument.

Parameters:

dbl - the value to be represented by this DoubleRep.

Throws:

java.lang.NumberFormatException - if d is either infinite or not a number.

See Also:

Double(double)

DoubleRep

DoubleRep(java.lang.String dStr)

Constructs a newly allocated DoubleRep object that represents the floating-point value of type double represented by the string. The string is converted to a double value as if by the method Double.valueOf(java.lang.String).

Parameters:

dStr - a string to be converted to a DoubleRep.

Throws:

java.lang.IllegalArgumentException - if d is either infinite or not a number.

java.lang.NumberFormatException - if d has not the appropriate number format.

Double(String)

DoubleRep

DoubleRep(java.lang.Double dbl)

Creates a new DoubleRep. An analog to DoubleRep(double).

Parameters:

dbl - a Double object.

Throws:

java.lang.IllegalArgumentException - if d is either infinite or not a number.
