Methods
-
abs()
→ double
-
Return the absolute value of this complex number.
Returns
NaN if either real or imaginary part is NaN
and double.INFINITY if neither part is NaN,
but at least one part is infinite.
override
-
argument()
→ double
-
Compute the argument of this complex number.
override
-
conjugate()
→ Cartesian
-
Return the conjugate of this complex number.
The conjugate of
a + bi is a - bi.
override
-
exp()
→ Cartesian
-
Compute the exponential function
of this complex number.
override
-
log()
→ Cartesian
-
Compute the natural logarithm
of this complex number.
override
-
noSuchMethod(Invocation invocation)
→ dynamic
-
Invoked when a nonexistent method or property is accessed.
inherited
-
pow(num x)
→ Cartesian
-
Returns of value of this complex number raised to the power of
x.
override
-
power<T extends Complex>(T z)
→ Cartesian
-
Returns of value of this complex number raised to the power of
x.
override
-
reciprocal()
→ Cartesian
-
Returns the multiplicative inverse of
this element.
override
-
sqrt()
→ Cartesian
-
Compute the square root
of this complex number.
override
-
sqrt1z()
→ Cartesian
-
Compute the square root
of
1 - this^2 for this complex number.
override
-
toString()
→ String
-
A string representation of this object.
override
Operators
-
operator *(Object factor)
→ Cartesian
-
Returns a
Complex whose value is this * factor.
Implements preliminary checks for NaN and infinity followed by
the definitional formula:
override
-
operator +(Object addend)
→ Cartesian
-
Returns a
Complex whose value is
(this + addend).
Uses the definitional formula
override
-
operator -(Object subtrahend)
→ Cartesian
-
Returns a
Complex whose value is
this - subtrahend.
Uses the definitional formula
override
-
operator /(Object divisor)
→ Cartesian
-
Returns a
Complex whose value is
(this / divisor).
Implements the definitional formula
override
-
operator ==(Object other)
→ bool
-
The equality operator.
override
-
operator unary-()
→ Cartesian
-
Negate operator. Returns a
Complex whose value is -this.
Returns NAN if either real or imaginary
part of this complex number equals double.nan.
