Decimal converted to any number of digits less than or equal to nine #includeThe C + + implementation converts a decimal number to any binary that is less than or equal to nine

1. Questions:This happens in the usual code, and the result of parsefloat (11.3-10.1) operation is still 1.200000000000001.code example:var arr = [0.0111,11.002,0.3,1.5,1.61var 0 = ={ + + Item }) Console.log (total) The result of the return---14.423100000000002, which is illogical.2. Solution:Here's a practical workaround for some floating-point application functions in math such as: parsefloat () and Math.floor ()The code is as follows:var arr = [0.0111,11.002,0.3,1.5,1.61var 0 = ={

Question: Enter an integer n to calculate the number of times 1 appears in the decimal representation of the N integers from 1 to n. For example, input 12, integers from 1 to 12 contain numbers 1, 10, 11, and 12, and 1 appear 5 times in total. If n = 23106 is required, the calculation process is as follows: Tens of thousands = 1:10000 --19999 total 10000 Thousands = 1:01000--21999 for a total of 3*1000 =

typescript, coupled with support for ES6, so need to introduce a lot of compatibility, and then submitted to the system, the system needs to verify that the origin and other origin overlap, overlap more than 10 % will be warned that the origin has been XXX registered in storage. The data measured by GPS measuring instrument is continuous longitude and latitude coordinate data. Now the question is translated into whether there is an intersection between a series of points and other regions. To g

The first behavior of the input file is an integer n, which indicates that the input file is followed by n sets of data, no group of data contains a maximum of 100 rows, each line has a very long decimal integer, the length of the integer is no more than 100 characters, and contains only numbers, the last behavior of each group of data 0, indicating the end of the setFor each set of data on the input file, output their and.This problem is different fr

I have not found such a function in JS I used to make up a truncated decimal function, the code is as follows /***********************************************************Function FormatNumber (value,num) Written by zerglingThe JavaScript version of the FormatNumber function is the same as VBScript, the first parameter is the value to be formatted, and the second is the number of

Question: Enter an integer n to calculate the number of times 1 appears in the decimal representation of the n integers from 1 to n. The efficiency is as high as possible. For example: F (2) = 1 F (12) = 5 F (20) = 12 F (115) = 44 Solution: The simplest method is to process from 1 to n cyclically, calculate the number of 1 in each

During js development, we sometimes need to obtain the integer part of a decimal number. In this case, we can use the js ceil method to obtain the part. The ceil () method performs an integer rounded up and returns a value greater than or equal to the function parameter and the nearest integer. This article introduces the use cases of ceil () in js. For more information about the coders, see. Ceil () return

Title: input: Integer a output: integer b Condition: A and B are the same number of binary 1, and the distance between A and B | a-b| minimum. Ideas:According to test instructions, the number of binary 1 of a and B is the same and requires a minimum distance, then the difference between A and B lies in the adjacent bit bits, such as 1100 and 1010,0011 and 0101.When the last digit of a (low) is 0, the last (

In c we can use printf ("%.2lf", a), but in C + + there is no format operator, what to do:C + + uses the Setprecision () function and must contain the header file Iomanip, as follows:#include "Iomanip"using namespace Std;......COUT.SETF (ios::fixed);//If you need to automatically fill 0, the definition of 0 before coutcout C + + cout Specifies the number of digits after the decimal point
