Floating-point precision processing in ACM

In ACM, accuracy issues are very common. Where the calculation of the geometric headache is generally the size of the code and the accuracy of the problem, code, as long as the usual attention to accumulate template is not a problem. Accuracy problem is not good to say, sometimes a precision problem may become a bottleneck, so you debug half a day can not find the error.1. Why do floating point numbers have precis

High Precision computing (1) -- Introduction

Label: style blog color use for strong SP data Div We know that at present, the computer computing value has a high accuracy, but due to hardware restrictions, it is often unable to meet the actual production needs, so we can achieve high-precision computing through careful design of the program. Let's talk about this issue today. First, we should know that,Working principle of high-precision computing: Lik

Analysis and solution of Javascript floating-point arithmetic precision problem _javascript skill

Analysis JavaScript has only one numeric type number, and all numbers in JavaScript are represented in the IEEE-754 standard format. The precision problem with floating-point numbers is not JavaScript-specific, because some decimal digits are infinite in binary notation: Decimal binary0.1 0.0001 1001 1001 1001 ...0.2 0.0011 0011 0011 0011 ...0.3 0.0100 1100 1100 1100 ...0.4 0.0110 0110 0110 0110 ...0.5 0.10.6 0.1001 1001 1001 1001 ...

High-Precision computing-subtraction (continued)

Based on the previous post, the modification and subtraction operations are suitable for high-precision floating point computing. Because the subtraction method is more difficult than the addition method, more considerations are required, and the code may be lacking. Operation description: 1. The subtraction function remains unchanged, including the size function used to determine the subtrahend and subtravers. 2. added two functions: the decimal poin

[. Net] How to Use C # for high-precision timer

Introduction This article describes how to use C # For a high-precision timer. Sometimes we need a timer with higher accuracy and sleep, but the sleep is not accurate. So I had to customize it myself. Background In general systems, sleep (1) is equivalent to 15.625 ms (1/64 seconds), that is, sleep (15) is the same as sleep.
