--description--

Given is the function f(x) = ⌊230.403243784-x2⌋ × 10-9 ( ⌊ ⌋ is the floor-function),

the sequence un is defined by u0 = -1 and un+1 = f(un).

Find un + un+1 for n = 1012. Give your answer with 9 digits after the decimal point.

--hints--

euler197() should return 1.710637717.

assert.strictEqual(euler197(), 1.710637717);

function euler197() {

  return true;
}

euler197();
