How to find the accuracy of decimal places between the integral approximation and the MATLAB built-in integral function? Eg: if my approximation is 0.50000000 and the true value is 0.52359878, and error is 0. 0 2359878, there is one 0 in front of the error value, '0.0', so the Decimal place will be 1, and when approximation is 0.51666667, error will be 0. 00 693211, there is two 0 , so decimal place will be 2.
Also, how do i only print the approximation and the error values when the decimal place has increased by 1?
