I was trying to simplify the term [1.0 - [s_{0} - [1.0 - 0.0] / [2.10526]] * [2.10526]] / [2.10526 - 1.0] in Aljava.

As a result I am getting 60511419/95738581 * s0 + 100000/55263 ( 0.6320484215240249 s0 + 1.8095289796066083) instead of 1.90476449 s0 + 1.8095289796066083.

In general I experienced more of those bugs whenever the integers in the fractions are rather large.

Expression const_1_left = new Expression(10).div(new Expression(10));

Expression var = new Expression("s0");

Expression frac_0 = new Expression(210526).div(new Expression(100000));

Expression const_0 = new Expression(0).div(new Expression(10));
Expression const_1 = new Expression(10).div(new Expression(10));
Expression num = const_1.minus(const_0);
Expression frac = new Expression(210526).div(new Expression(100000));
Expression result_end = num.div(frac);
Expression result_im = var.minus(result_end);
Expression result_im2 = frac_0.times(result_im);
Expression result_num = const_1_left.minus(result_im2);

Expression denom_left = new Expression(210526).div(new Expression(100000));
Expression denom_right = new Expression(10).div(new Expression(10));
Expression denom = denom_left.minus(denom_right);

Expression result = result_num.div(denom);

System.out.println(result);
