特異メソッド

定義 説明

Creates a Complex number in terms of r (radius) and theta (angle).

rect
rectangular

インスタンスメソッド

定義 説明
self * other

Multiplication with real or complex number.

self ** other

Raise this complex number to the given (real or complex) power.

self + other

Addition with real or complex number.

self - other

Subtraction with real or complex number.

-
self / other

Division by real or complex number.

self == other

Test for numerical equality (a == a + 0i).

abs

Absolute value (aka modulus): distance from the zero point on the complex plane.

abs2

Square of the absolute value.

angle
arg

Argument (angle from (1,0) on the complex plane).

coerce(other)

Attempts to coerce other to a Complex number.

conjugate
conj

Complex conjugate (z + z.conjugate = 2 * z.real).

denominator

FIXME

eql?
fdiv
hash

Returns a hash code for the complex number.

imag
imaginary
inspect

Returns "Complex(real, image)".

magnitude
marshal_dump
marshal_load
numerator

FIXME

phase
polar

Returns the absolute value and the argument.

quo(other)
real
real?
rect
rectangular
to_f
to_i
to_r
to_s

Standard string representation of the complex number.
