The last digit is correct to the display precision.  What you are asking for is
how to display an additional digit.

InputForm[13505.5-244.91]

13260.59

NumberForm[13505.5-244.91,7]

13260.59

13505.5`7-244.91`7

13260.59

However,13505.5 - 244.91 = 13260.59. "N" doesn't help, either.

In[25]:= N[13505.50 - 244.91]
Out[25]= 13260.6

But the following command gives the correct answer.
In[26]:= 505.50 - 244.91
Out[26]= 260.59
