title: In MIPS, what are HI and LO
body: <p>I'm reading about division in MIPS and I've found that div</p>
  <blockquote>
  <p>Divides $s by $t and stores the
  quotient in $LO and the remainder in
  $HI</p>
  </blockquote>

  <p>And Wikipedia says</p>
  <blockquote>
  <p>HI and LO are used to access the multiplier/divider results, accessed by the mfhi (move from high) and mflo commands.</p>

  <p>Are HI and LO registers?  What number registers are they?</p>
