Complex#denominator

() -> ::Integer

denominator → integer

static VALUE
nucomp_denominator(VALUE self)
{
    get_dat1(self);
    return rb_lcm(f_denominator(dat->real), f_denominator(dat->imag));
}

Returns the denominator of self, which is the least common multiple of self.real.denominator and self.imag.denominator:

Example

Complex.rect(Rational(1, 2), Rational(2, 3)).denominator # => 6

Note that n.denominator of a non-rational numeric is 1.
