arr calculation

Recent work has often encountered the need to deal with floating-point calculation problem, began to use the floating-point number is multiplied by 10 of the corresponding fractional digits of the decimal integer to start the calculation.For example 100.01+100.02, can be converted into (100.01*100+100.02*100)/100来 To do the calculation, but recently sent a floating point number multiplied by a 10 of the tim

Using Python to draw ROC curve and AUC value calculation, rocauc Preface The ROC curve and AUC are often used to evaluate the merits of a binary classifier. This article will first briefly introduce ROC and AUC, and then use an example to demonstrate how to create a ROC curve and calculate AUC in python. AUC Introduction AUC (Area Under Curve) is a very common evaluation indicator in the Machine Learning binary classification model, compared with the

Title DescriptionDescription addition and subtraction is the basic operation in the calculation, although the rules are simple, but the number of bits is too many, it will inevitably make mistakes. The question now is: given any number of digits (no more than 1000 bits) of the addition and subtraction formula, give the correct result. To increase the speed, the result of the given operation is guaranteed to be a positive integer. input/output format i

Several power function calculation methods and Power Function MethodsIntroduction We know that the Base e of the natural logarithm is defined as the following limit value: This formula is suitable for some tests on power function calculation. The result is an approximate value of e, so you don't have to worry that the calculation result will overflow when n is l

Numerical calculation refers to the algorithm in the field of numerical analysis. Numerical analysis is a special study of data problems related to numerical and approximate values, and numerical calculation plays a particularly important role in the study of numeric analysis.polynomial interpolation is a method of calculating the approximate value of a function . Where the function value is known only on a

WPS Word is one of our common Office software, because of its simple, practical, so well received by the user's favorite. When we edit a document, we sometimes need to insert a table in the document, compare or assist some data, and then count some of the data in the table. For the calculation of the data in the table, we usually are accustomed to using Excel to operate, thus ignoring the WPS text in the table cal
