Is it possible to limit coefficients as Integers from Engle-Granger test of Johansen test?

I am trying to use egcitest or jcitest to solve the cointegration relationship with 2 sets of data. it turns out the coeffcients are always with decimals. is it possible to get the best possible integer solution? I know it will not be as accurate, but I need only the integer solution. by rounding off the coefficients is not an option since there may be another set of integers fits better.

if it is not possible, are there any regression models I can restrain the solution as integers?

thanks in advance.
