The integer values are just being displayed in the exponential form (scientific notation).
You can disable it as shown here:
x = torch.tensor([[2.7900e+02, 1.2800e+02, 3.6000e+01], 
                  [1.0000e+00, 7.3100e+02, 3.6000e+01],
                  [1.0900e+02, 1.3400e+02, 1.4860e+03]])

print(x)
torch.set_printoptions(sci_mode=False)
print(x)
