`Element.div` is wasting floating point precision on trivectors with length 1

[kungfooman]

There is this "trick" to solve linear equations in all kinds of GA books:

GAmphetamine(3, () => {
  // --- Vektor Definitionen (Spalten) ---
  const v0 = 2*1e1 + 5*1e2 + 3*1e3;
  const v1 = 3*1e1 + 1*1e2 + 2*1e3;
  const v2 = 4*1e1 + 6*1e2 + 1*1e3;
  const target = 32*1e1 + 47*1e2 + 18*1e3;
  // --- Nenner-Volumen berechnen ---
  const vol = v0 ^ v1 ^ v2;
  console.log("Volumen: ", vol);
  // --- Lösungen berechnen (Zähler / Nenner) ---
  // Variable 0
  const num0 = target ^ v1 ^ v2;
  const ans0 = num0 / vol;
  console.log("num0: ", num0);
  console.log("135/45", 135/45); // 3
  console.log("Ergebnis Variable 0: ", ans0); // 3.000000072643161
  // Variable 1
  const num1 = v0 ^ target ^ v2;
  const ans1 = num1 / vol;
  console.log("Ergebnis Variable 1: ", ans1);
  // Variable 2
  const num2 = v0 ^ v1 ^ target;
  const ans2 = num2 / vol;
  console.log("Ergebnis Variable 2: ", ans2);
});

Result:

Ergebnis Variable 0:  3.000000072643161
Ergebnis Variable 1:  2.000000048428774
Ergebnis Variable 2:  5.000000121071935

Instead of calculating 3 it's calculating 3.000000072643161 because it goes through the entire inverse. But it's both just two trivectors with one number component anyway:

We should be able to just check if both element have length 1 and do "normal" division?
