[ntp:questions] NTP timestamp format

Hello,

in NTP FAQ 5.1.2.3. (http://www.ntp.org/ntpfaq/NTP-s-algo.htm) it is
standing:
[...]
00000000000000000000000000000001 10000000000000000000000000000000

equals a decimal 1.5. The multipliers to the right of the point are
1/2, 1/4, 1/8, 1/16, etc.
[...]

If I understand it right, the binary calculation goes then from
left-to-right, so it represents the normal binary, like
00000000000000000000000000000001 (1 in decimal); but why is the
multiplier then 1/2? And how should the other multiplier looks like
(e.g. 1/4; I would have thought it has to be
00100000000000000000000000000000 then?!)

As far as I understand, the integer part is calculated as a normal
binary (001 = 1, 010 = 2, etc.)

Can somebody clearify the order of bits in NTP for me, please?

Thanks in advance!
Franz
