C++ boost::multiprecision::cpp_dec_float
Header file #include<boost/multiprecision/cpp_dec_float.hpp>
->This function is used for working with float values having larger precision.
->The value of the precision is given by user given as
cpp_dec_float_100,cpp_dec_float_50,cpp_dec_float_25 which are inbuilt in boost library.
->This program is given for calculating the area of the circle with higher precision.
->As the precision value gets higher the chances of error in calculation becomes less therefor,this function is very helpful in calculation manner.
