The equivalent of SP->xs = malloc(size * sizeof(double)); is SP->xs = new double[size]; This does not require any #includes. To free the allocated array, use delete[]: delete[] SP->xs; The square brackets are important: without them, the code will compile but will have undefined behaviour. Since you’re writing in C++, consider using std::vector<double> instead of managing … Read more
You can use the following approach For Example package main import ( “fmt” “strconv” ) func main() { str := []byte(“0125”) aByteToInt, _ := strconv.Atoi(string(str)) fmt.Println(aByteToInt) } You can run following code here https://play.golang.org/p/iq8Q9PkhM43 solved How to convert byte type value to int type value
By doing ((aStr = $(printf %03d $a))), you are destroying again the careful formatting done by printf. You would see the same effect if you do a (( x = 005 )) echo $x which outputs 5. Actually the zeroes inserted by printf could do harm to your number, as you see by the following … Read more
This should fix your problem (if I understand the problem, that is): var number = decimal.Parse(“0,55”.Replace(‘,’, ‘.’), CultureInfo.InvariantCulture); EDIT Not every culture uses the point (.) symbol as the decimal separator. If you don’t specify a format provider, the framework defaults to the current culture. I’m guessing that in this particular case, the decimal.Parse() method … Read more
Multiprocessing is a way to get it done faster (in addition of using Numpy): E.g: In [11]: from multiprocessing import Pool In [12]: pool = Pool(10) In [13]: pool.map(int, [str(i) for i in range(500)]) Numpy will mostly provide a memory gain as you would be dealing with primitive types instead of python objects, but will … Read more
You can use PHP array_column function with combination of implode: implode(‘, ‘, array_column($data, ‘post_id’)); solved Array key value to string in PHP [duplicate]
This answer presumes the C implementation uses a 32-bit int and a 64-bit long. C 2018 6.4.4.1 says “The type of an integer constant is the first of the corresponding list in which its value can be represented.” In the table that follows, the entry for decimal constants with no suffix contains the list int, … Read more
As Crockford says: “The rules by which they do that are complicated and unmemorable.” The spec defines them all in section 11.9.3 (pointed out by @Oriol in a comment to OP). For the two cases you provided: if ( 42 == true ) // false ( Only 1 is true ) if ( “Hello World” … Read more
I’ve finally found the correct VBA I was looking for: ‘In your VBA window go to tools then references and add a reference to ‘Microsoft Word Sub Converter() Dim cnt As Integer, currfile As String Dim TrimFile As String, Path As String, FilesInPath As String _ , MyFiles() As String, Fnum As Long Dim CalcMode … Read more
Let’s say the time zone offsets are valid, they are in hours and minutes always separated by a colon (‘:’) and preceded by a ‘+’ or ‘-‘. So var utcOffset = “+05:30”; var a = uctOffset.split(‘:’); var hour = +a[0]; var minute = +a[1]; What you do with the hour and minute values is up … Read more
The hex represents a double in little-endian format. If you reverse the bytes and check against your first result you will see that it matches the decimal representation: http://binaryconvert.com/result_double.html?hexadecimal=4049689F80000000 1 solved Converting binary data to numeric format [closed]
Problem: -5000m is a negative number, which is outside the range of UInt64 (an unsigned type). Solution: use Int64 instead of UInt64 if you want to cope with negative numbers. Note that you can just cast instead of calling Decimal.To…: long x = (long) (production – expense); Alternative: validate that the number is non-negative before … Read more
Here is a very simple example to process your file and split the string line and obtain the date object. public class FileReaderExample { public static void main(String[] args) { File file = new File(“d:\\text.txt”); try { BufferedReader br = new BufferedReader(new FileReader(file)); String line; int lineNo = 1; while ((line = br.readLine()) != null) … Read more
I think this link should give you an insight: Why Are Floating Point Numbers Inaccurate? It is understandable since the results can be slightly different due to precision if compared between how different languages deal with them. A quick example between using in python and just googling the answer: Python example Google example solved Why … Read more
