Research And Develop On The System Of The Big Integral's Calculating Accurately

Because the value that"big integral"outran the procedure design language integral type gathers the scope. It is hard to realizes it's expressing, saving, read, process, output etc. using generally method.As for the complexity of the big integral process system and the big integral system used for the high technique realm generally, so systematize the research and development of the big integral system concentrates primarily to calculation in some national class center, safe center. But extends gradually along with the applied realm of big integral and the fast development of the personal calculation ability, this work has been under observation of more and more technologies worker.The technique project and key algorithm of big integral process system investigated by calculation center or safe center of the national class is very sencitive, so the application also limits at the large calculator generally, without very strong and general use.The technology workers of many different realms also forward the some way of big integral process method on demand of work of hisself, especially the workers in encrypting and declassifying do a very big contribution for pushing the technical of process the big integral and fast development. However because of encrypting and declassifying considers the system to support the hardware more, its method exsits localization in the aspects of data compress ability.And workers in general realm especially calculator realm with the technology of the application mathematics realm worker also develop some small big integral process procedure because of teaching or scientific research or for interest. However, the handling ability of these system is limited or systems are not enough complete or with weak usability.For this, this paper studies expressing and processing problems of big integer in the common PC class calculator including the big integral add, reduce, multiplies by, divide, exponent, mold, etc., and big integral and normal regulations integral of four carries to calculate the problem. For the sake of the convenience of developping two times, this paper still researches middleware technique. Based on the study, the big integral system which is precise to carry calculation has been developed completedly with strong ability of handling, high speed of calculation, usage convenience, flexible structure...
