title: Sending Float/Double Values Across CANbus
body: <p>I am preparing a code that sends various electrical parameters across a CANbus (power, voltage, current, etc.). Precision is necessary for this circumstance.</p>
  <p>There are two options I see:</p>
  <ol>
  <li>Send the value as an integer, but scale it on sending and receiver side (Sending x100, Receiving /100, for example). If I do this, then I can send 2.12V as 212 (or 0xD4).</li>
  <li>Send it as a float value, which would require 32 bits but no scaling.</li>
  </ol>
  <p>My questions are as follows:</p>
  <ol>
  <li>Can float values be sent across CANbus?</li>
  <li>If yes to Q1, is that a common practice? Or do most CANbus communication programmers use scaled integers?</li>
  </ol>
  <p>Thank you in advance.</p>
