How to increase precision of output produced by LINPROG ?

Hello, I am solving LP problems by using linprog command. In some problems the output is quite big so the answer received is in the form like "2.7719e+06".

dec_vars=linprog(f,A,b,Aeq,Beq,lb,ub,x0)

This is the standard code to use linprog and the values entered in each of f,A,b.. and so on are all integers. Just to clarify again, the answer I get is right but its usually off by a 2-3 digit number. How do I avoid it and ensure the exact whole answer is visible?

Thanks
