• Method Detail

  • unit

    public final Unit unit()

    Overrides:

    unit in class Quantity

  • number

    public final Complex number()

    Specified by:

    number in class Quantity

  • re

    public final RealNum re()

    Description copied from class: Quantity
    The value of the real component, as a RealNum. The unit() is not factored in, so you actually need to multiply by unit() to get the true real component.

    Overrides:

    re in class Quantity

  • doubleValue

    public final double doubleValue()

    Description copied from class: Quantity
    The value of the real component, as a double. This is relative to the unit().dims - i.e. unit()/doubleValue() is factored in.

    Overrides:

    doubleValue in class Quantity

  • isExact

    public boolean isExact()

    Specified by:

    isExact in class Numeric

  • isZero

    public boolean isZero()

    Specified by:

    isZero in class Numeric

  • add

    public static DQuantity add(DQuantity x,
     DQuantity y,
     double k)

  • times

    public static DQuantity times(DQuantity x,
     DQuantity y)

  • divide

    public static DQuantity divide(DQuantity x,
     DQuantity y)

  • add

    public Numeric add(java.lang.Object y,
     int k)

    Description copied from class: Numeric
    Return this + k * obj.

    Overrides:

    add in class Quantity

  • addReversed

    public Numeric addReversed(Numeric x,
     int k)

    Description copied from class: Numeric
    Calculate x+k&this.

    Overrides:

    addReversed in class Quantity

  • mul

    public Numeric mul(java.lang.Object y)

    Overrides:

    mul in class Quantity

  • mulReversed

    public Numeric mulReversed(Numeric x)

    Overrides:

    mulReversed in class Quantity

  • div

    public Numeric div(java.lang.Object y)

    Overrides:

    div in class Quantity

  • divReversed

    public Numeric divReversed(Numeric x)

    Overrides:

    divReversed in class Quantity

  • writeExternal

    public void writeExternal(java.io.ObjectOutput out)
     throws java.io.IOException

    Specified by:

    writeExternal in interface java.io.Externalizable

    Throws:

  • readExternal

    public void readExternal(java.io.ObjectInput in)
     throws java.io.IOException,
     java.lang.ClassNotFoundException
