understanding the output of: gpart list da0

Hello,

I have here the output (a bit shorted and with added calculations)
of 'gpart list da0':

1. Name: da0p1
   Mediasize: 524288 (512K)   512K = 512*1024 = 524288 = length
   index:  1
   start:  1953523712
   end:    1953524735
   length: 524288

2. Name: da0p2
   Mediasize: 274877906944 (256G)  256G = 256*1024*1024*1024 = 274877906944 = length
   index:  2
   start:  2048
   end:    536872959
   length: 274877906944

3. Name: da0p3
   Mediasize: 41943040 (40M)    40M = 40*1024*1024 = 41943040 = length
   index:  3
   start:  536872960
   end:    536954879
   length: 41943040

4. Name: da0p4
   Mediasize: 723177701376 (674G)  674G = 674*1024*1024*1024 = 723701989376 != length
   index:  4
   start:  541067264
   end:    1953523711
   length: 723177701376


What I do not understand is:

1) Why differs the 'length' of da0p4 from the real value for 674G?

2) All the values for 'start', 'end' and 'length' does not make any
sense to me.

Can someone enlighten me a bit.

Thanks

	matthias
