Precision Calculation-big number multiplied by large number, precision calculation by large numberThe algorithm is used to calculate a large number (a number that cannot be expressed by an existing data type) multiplied by a large number (a number that cannot be expressed by an existing data type ). The algorithm is to put every bit of a large number as a character into a character array, and then multiply

++ and Python language constants; Mathematica, MATLAB and Octave; Various textbooks-see below for the latter definitionIf you use extension software tools such as GMP/MPIR/MPFR to increase the accuracy of the actual participation in the calculation, use Pavel C + + wrapper mpfrc++ (it's strange that his profile only involves technology-related information is also blocked), combined with eigen C + + template The library is my favorite.https://code.goog

we assume that the Earth is a perfect sphere, its radius is the mean radius of the Earth, which is recorded as R. If the zero-degree longitude line is used as the basis, the distance between the two points can be calculated based on the latitude and longitude of any two points on the Earth's surface. (here, the error caused by the calculation of the earth's surface topography is ignored, only theoretical estimates ). Set the longitude and latitude of
