Modification of grid method with changing some floating parameters to their integer analogs is obtained. It can increment a count of cells in 3D grid by 40 % without a computing memory upgrade. This modification has a control limited error, but approximation order is saved. Testing results on Dirichle problem and on Godunov method for 2D Euler equations are presented.
