Abstract
A calculation method suitable for use in statistics calculations and a calculator using the method are disclosed. The method has the steps of storing a memory content from a memory in a first register of a calculation circuit; storing input data in a second register of the calculation circuit; performing a calculation on the contents of the first register and the second register, and storing the result of the calculation in the first register; determining that the calculation result stored in the first register has not overflowed; transferring the content of said first register to the memory and overwriting the memory content therewith, if the calculation result has not overflowed after the processes have been repeated a specified number of times. The calculator has an input section for inputting data; a calculation section for performing a specified calculation on the data; an overflow determination section for determining whether or not a calculation result that is the result of the calculation has overflowed; a calculation totalling section for determining whether or not the calculation has been performed a specified number of times; and a memory section for storing the calculation result obtained by the calculation means, if the calculation totalling means has determined that the calculation has been performed the specified number of times.
