instance method

Complex#real

() -> ::Numeric

real → numeric

VALUE
rb_complex_real(VALUE self)
{
    get_dat1(self);
    return dat->real;
}

Returns the real value for self:

Example

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

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

Example

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