instance method

Complex#imag

() -> ::Numeric

imag → numeric

VALUE
rb_complex_imag(VALUE self)
{
    get_dat1(self);
    return dat->imag;
}

Returns the imaginary value for self:

Example

Complex.rect(7).imag     # => 0
Complex.rect(9, -4).imag # => -4

If self was created with polar coordinates, the returned value is computed, and may be inexact:

Example

Complex.polar(1, Math::PI/4).imag # => 0.7071067811865476 # Square root of 2.
