This can be avoided by transforming the formula into -\f[y_i = {(\sum_{j=0}^{j=i} x_j) a \over b} - \sum_{j=0}^{j=i} y_j\f] +\f[y_i = {(\sum_{j=0}^{j=i} x_j) a \over b} - \sum_{j=0}^{j=i-1} y_j\f] Of corse, when all \f$y_i\f$ are calculated in a sequence, -\f$\sum_{j=0}^{j=i} x_j\f$ and \f$\sum_{j=0}^{j=i} y_j\f$ can be +\f$\sum_{j=0}^{j=i} x_j\f$ and \f$\sum_{j=0}^{j=i-1} y_j\f$ can be accumulated in the same loop. */
