title: Why doesn't the decimal class use the remaining 26 bits?
body: <p>The decimal class uses 96 bits for the integral part, 1 bit for the sign, and 5 bits for the scaling factor. 26 bits are unused, and the max value is 7.9e28 because the maximum exponent is 28.    </p>
  
  <p>Using the other 26 bits, the precision would be higher. What's the reason for this implementation choice?</p>
