MATLAB: Do i get decimal on the final answer

beginner

The final asnwer should be 200, 1400 and 600. But why there is decimal in my final matlab answer? Did I left something?
A = [ 1 1 1 ; 0.06 0.08 0.09 ; 3 0 -1]
A =1.0000    1.0000    1.0000
    0.0600    0.0800    0.0900
    3.0000         0   -1.0000
>> B= [ 2200 ; 178 ; 0]
B = 2200
         178
           0
>> AB = [ A B ]
AB =1.0e+03 *
    0.0010    0.0010    0.0010    2.2000
    0.0001    0.0001    0.0001    0.1780
    0.0030         0   -0.0010         0
>> rref(AB)
ans =1.0e+03 *
 0.0010         0         0    0.2000
         0    0.0010         0    1.4000
         0         0    0.0010    0.6000
