1. Question requirements Enter the sum of two decimal numbers of any length (within 20 digits) on the keyboard. Use “-” to identify negative numbers. Positive numbers can be left unsigned or added with a “+” sign. (Assembly language programming environment used: Masm for Windows integrated experimental environment 2012.5) 2. Question Analysis This question requires […]

Do “Numbers retain specified decimal places” via BigDecimal
Requirements: Keep the obtained Double type value to 2 decimal places without rounding Proposal: Precise number calculation and formatting with BigDecimal public static void main(String[] args) { double num = 14.5684; int decimalPlaces = 2; // Reserve 2 digits BigDecimal bd = new BigDecimal(Double.toString(num)); bd = bd.setScale(decimalPlaces, BigDecimal.ROUND_DOWN); // Keep 2 decimal places and do […]
Solution/algorithm {\255. Kth decimal}
Solution/algorithm {\255. Kth decimal} @LINK: https://www.acwing.com/problem/content/description/257/; For array A, find the Kth decimal in the interval A[l…r]; . For example, A = [5,3,2,3,1], for A[123] = [2(1st decimal), 3(1st decimal) 2nd smallest), 3(3rd smallest)]; Algorithm-(persistent segment tree + weighted segment tree) 1: Discretize the array into [0, Range); (of course if min(A)>=0 & amp; & […]
8086 assembly-the user inputs any number between 1 and 100 and completes the decimal result output
The user inputs any number between 1 and 100, and the decimal result is output The general idea is to read user input, process it into decimal numbers, and output it to the screen. First, the user’s input needs to be read. Initialize the memory and registers, clear the data in them, and read the […]
JS decimal operation precision loss problem
In your work, do you often encounter the calculation of some data indicators, such as percentage conversion, how many decimal places to keep, etc.? Then the calculation will be inaccurate and the data precision will be lost. Through this sharing, the problem of data accuracy loss can be easily solved with the help of third-party […]
Hexadecimal (base conversion) (Python)
Hex 1. Base conversion Let’s look at decimal and binary first (1) The essence of base conversion We use short division to convert decimal to binary. “Number system” is just a system of symbols to represent the amount of the referenced “quantity”. We use the symbol “1” to represent this concept of “quantity”. The “quantities” […]
Java: Use the BigDecimal class to cleverly handle the precision loss of the Double type
Key points of this article Briefly describe the reasons why precision is lost when converting floating point from decimal to binary. Introduce the differences between several ways to create BigDecimal. A collection of tools for high-precision calculations. I learned the provisions of Alibaba Java Development Manual on BigDecimal equality. Classic problem: loss of precision of […]
C language implements quaternary (quadtree) and decimal Morton codes
1. Foreword: It was introduced by “Geographic Information Systems and Principles” and “Basics of Geographic Information Systems”. It seemed a bit interesting, so I wanted to implement it in C language and sort out the relevant content. Prerequisite knowledge: Leaf node: A node that has no child nodes. The linear quadratic number only stores the […]
