Method Detail

make

public static DFloNum make(double value)

doubleValue

Overrides:
doubleValue in class Complex

longValue

public long longValue()
Overrides:
longValue in class Complex

hashCode

public int hashCode()
Overrides:
hashCode in class java.lang.Object

equals

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

Specified by:
add in class RealNum

addReversed

public Numeric addReversed(Numeric x,
                           int k)
