Constructor Summary

ComplexOps()

 

Method Summary
Complex	add(Complex b)           Return this + b (the sum of this and b).
Complex	div(Complex b)           Return this/b (the quotient of this by b).
boolean	equals(Object o)           Return true if these are the same complex number.
int	hashCode()           Return a hashCode for this number.
Complex	mul(Complex b)           Tell whether the given angles are the same, taking into account that angles measured in radians wrap around after 2*StrictMath.PI times.
Complex	sub(Complex b)           Return this - b (the difference between this and b).
