[Scilab-users] Bitget for int64/uint64

[JLan]

I wonder if i have misunderstood the documentation for bitget, or if this is
a bug? It seems to me that numbers > 2^53 are still not handled correctly.
--> a=uint64(2^61)
 a  =   2305843009213693952
--> b=uint64(2^61)+1
 b  =   2305843009213693953
--> bitget(a,1:64)
 ans  =
         column 1 to 32
  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0 
0  0  0  0  0  0  0
         column 33 to 64
  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0 
0  0  0  0  1  0  0

--> bitget(b,1:64)
 ans  =
         column 1 to 32
