That str2num output looks right for format short. You overlooked the scale factor at the top of the display of that matrix.

>> format short
>> 40220151038 + [0; 1]
ans =
   1.0e+10 *
    4.0220
    4.0220

Try using display format longg instead of the default format short.

>> format longg
40220151038 + [0; 1]
ans =
               40220151038
               40220151039
