- * NTP uses two fixed point formats. The first (l_fp) is the "long"

- * values, which is a big hack but saves rewriting all the operators
- * twice. Just to confuse this, we also sometimes just carry the
- * fractional part in calculations, in both signed and unsigned forms.
- * Anyway, an l_fp looks like:
- *
- * 0 1 2 3
- * 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1
