Complex#to_i

() -> ::Integer

to_i → integer

static VALUE
nucomp_to_i(VALUE self)
{
    get_dat1(self);

    if (!k_exact_zero_p(dat->imag)) {
        rb_raise(rb_eRangeError, "can't convert %"PRIsVALUE" into Integer",
                 self);
    }
    return f_to_i(dat->real);
}

Returns the value of self.real as an Integer, if possible:

Example

Complex.rect(1, 0).to_i              # => 1
Complex.rect(1, Rational(0, 1)).to_i # => 1

Raises RangeError if self.imag is not exactly zero (either Integer(0) or Rational(0, _n_)).
