In olden days the processor size depends upon the length of the calculation of problem. Here I would like to tell you that the chip of the processor had reduced its size where this calculator have grown in functionality. As per the technology these devices are being used for a modern scientific calculator. These processors are used to involve all the functional modes of all calculations. What is a Scientific Calculator? A scientific calculator is a calculator specially designed to deal with scientific problems.
