. floatvalue (), of course, is still because of the loss of precision. Of course, if your decimal point is no more than 5 digits, it is also possible. If it is more than 5 digits, it is related to the value of the fifth digit (because it only keeps the five decimal places). If the fifth digit is greater than or equal to five, even if the sixth digit is zero, it will add one to the fifth digit, otherwise, the following will only be intercepted! Speaking of this, I suddenly think of the ending nu

approximate operation of some approximate values, rather than an exact operation in the previous arithmetic operation. Because of its nature and general situation, real-time floating-point data is only an approximate representation of the real number, which means that real-time floating-point operations are only an approximate operation. In this topic, the accuracy of the approximation is very high, and the calculation result is exactly the same as t

Java float addition and subtraction accuracy can be converted to bigdecimal when this field is obtained, while bigdecimal can be set.

MATLAB provides a wide range of data types (you can find detailed descriptions of MATLAB data types). The default data type is double. However, sometimes there may be situations where the data type is not accurate enough. For example, when calculating the slope and counting down, there may often be a phenomenon where the difference is a thousand miles. Therefore, the precision of existing data types needs to be improved. MATLAB provides a function VPA that allows you to customize data precision.

workaroundAt present, there are many solutions, but there is no solution to the bottom of the test. In general, the user's initial seed points are randomly given, or based on visual, that is, multiple clustering operations, the selection of the relatively optimal cluster, but this method is not automatic. At present, more research is to combine simulated annealing, genetic algorithm and other heuristic algorithms with Kmeans clustering, which can greatly reduce the dilemma of local optimization
