instance method

Complex#infinite?

cmp.infinite? → nil or 1

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

    if (NIL_P(f_infinite_p(dat->real)) && NIL_P(f_infinite_p(dat->imag))) {
        return Qnil;
    }
    return ONE;
}

Returns 1 if cmp‘s real or imaginary part is an infinite number, otherwise returns nil.

Example

For example:

   (1+1i).infinite?                   #=> nil
   (Float::INFINITY + 1i).infinite?   #=> 1
