title: How to convert voltage (or frequency) floating number read backs to mV (or kHz)?
body: <p>I am successfully able to read back data from an instrument:</p>
  <ul>
  <li><p>When the read back is a voltage, I typically read back values such as <code>5.34e-02</code> Volts.</p>
  </li>
  <li><p>When the read back is frequency, I typically read values like <code>2.95e+04</code>or <code>1.49e+05</code> with units Hz.</p>
  </li>
  </ul>
  <p>I would like to convert the voltage read back of <code>5.34e-02</code> to exponent e-3 (aka millivolts), ie.. <code>53.4e-3</code>. next, I would like to extract the mantissa <code>53.4</code> out of this because I want all my data needs to be in milliVolts.</p>
  <p>Similarly, I would like to convert all the frequency such as <code>2.95e+04</code> (or <code>1.49e+05</code>) to kiloHz, ie... <code>29.5e+03</code> or <code>149e+03</code>. Next would like to extract the mantissa <code>29.5</code> and <code>149</code> from this since all my data needs to be kHz.</p>
  <p>Can someone suggest how to do this?</p>
