First of all, I would like to thank Liu rujia for his book "algorithm competition getting started classic".
As we all know, the unsigned long with the largest storage capacity in C ++ also has an upper limit. If we want to calculate a very large integer, we will be overwhelmed, I wrote a high-
APP source code for QQ space of high imitation precision mobile phone edition, high imitation precision source code
Note: This QQ space has updated the previous basic code.Update content1. Updated the logon page.2. added the effect of playing audio when the password is entered and after the login is successful3. added the effect of gradually hiding the navigation bar (like the navigation bar of the real QQ
Precision Calculation-big number multiplied by large number, precision calculation by large numberThe algorithm is used to calculate a large number (a number that cannot be expressed by an existing data type) multiplied by a large number (a number that cannot be expressed by an existing data type ). The algorithm is to put every bit of a large number as a character into a character array, and then multiply
DescriptionStripping divided by high-precision
InputEach set of test data stack 2 rows, each row represents a high precision integer (no more than 100 bits)
OutputEach set of test data output accounted for 2 rows, respectively, the output quotient and the remainder.
Sample Input1405
Sample Output280
Ideas:Division is analog subtraction.First, the maximum multiplier (represented by 10^k) that can be subtract

Recently, at the 2016 Intel Life Science Information Technology Forum, a bio-computing accelerator platform called GTX one emerged, sparking new insights into the industry's precision healthcare industry. The GTX one acceleration system, which maximizes the computational power of the FPGA through algorithmic innovation, is equivalent to compressing a supercomputer into a small box, and an FPGA accelerator card can achieve the computational performance
The precision value of a floating-point number in PHP is used to control the output of the floating-point number. Can be understood as the control of the output of the number of digits, the difference in precision, see the output may also be different, note: its internal or in accordance with the actual value of storage, when two floating-point number for arithmetic, with its original value.
PHP's configur
In recent several posts, and QQ group discussion inside, I found that many users have encountered the problem is due to improper use of single-precision/double-precision values. So I want to talk about this topic specifically.Single-and double-precision numeric types first appear in the C language (in a more general language), and the single-
because the computer operation is a modulo operation, the representation of the data range is limited, such as int (c + + in the same int and long) expression range ( -2^31~2^31-1), unsigned long (unsigned integer) is (0~2^32-1), are about billions of. If a real type is used, the largest double can be saved to provide only a valid number of 15~16 bits, that is, only the number of trillions can be accurately expressed. Therefore, when the number of digits exceeding more than 10 bits is calculated
Many users have the experience of making CHM documents, perhaps to share information with others, or to help themselves develop software. Although the web search CHM production software results are numerous, but the real use is not much, can be called excellent only a few. Among them I think excellent and free only Precision Helper, called the best free CHM production software.
Why do you say it's good?

Single-precision floating-point numbers are 4 bytes (32bit) representing floating point numbersUses the IEEE754 standard computer floating-point number, in the interior is uses the binary system to representFor example: 7.22 with a 32-bit binary is not enough.So it's not accurate.

The following is a brief list of common recommended system metrics:
1. Accuracy rate and Recall rate (Precision Recall)
Accuracy and recall rates are two measures widely used in the field of information retrieval and statistical classification to evaluate the quality of the results. The accuracy is to retrieve the number of related documents and the total number of documents retrieved, to measure the precisio
Measurement uses accuracy, precision, and accuracy to evaluate and measure the quality of measurement results. The three terms are often confusing and their meanings are different.
· Accuracy-indicates the degree of consistency between the measurement result and the measured (agreed) true value, sometimes referred to as accuracy,
Reflects the degree of system error in the measurement results. High Accuracy means that the system error is small. At this
Let's look at two questions:
0.1 + 0.2 = 0.3; False9999999999999999 = 10000000000000000; True
The first problem is the problem of decimal precision, which has been discussed in many blogs in the industry. The second problem is that last year, the company had a system of databases in the data revisions, found that some of the strange phenomenon of duplication of data. This article will start from the specification, to the above question to make a sum
