The variable n inside the function is distinct from the expression (or variable) supplied as an argument. As such, assigning to n inside the function will not affect any of the variables outside. (This is because Python is not Call By Reference.) Instead, use the return value, eg. def classifyInput(n): if n == “r”: return … Read more
if you want decimal part do this . double value = 1.25; int i = (int)value; if you want to round value , do this Math.round(value); 8 solved How to get integer of a value? [closed]
The answer given by JoeFryer is one idea or else you can also use NSNotificationCenter. It works as below. Put this in ImageviewController Tap Action. [[NSNotificationCenter defaultCenter] postNotificationName:@”countUp” object:nil userInfo:nil]; Put this in MainViewController‘s ViewDidLoad method. [[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(increaseCount) name:@”countUp” object:nil]; and also this method -(void)increaseCount{ //Here You can increase the count count++; } Hope … Read more
decimal firstDecimal = 120.01M; double firstDouble = 120.01; float firstFloat = 120.01F; Console.WriteLine ((int)(firstDecimal * 100)); // 12001 Console.WriteLine ((int)(firstDouble * 100)); // 12001 Console.WriteLine ((int)(firstFloat * 100)); // 12001 Console.WriteLine (Convert.ToInt32(firstDecimal * 100)); // 12001 Console.WriteLine (Convert.ToInt32(firstDouble * 100)); // 12001 Console.WriteLine (Convert.ToInt32(firstFloat * 100)); // 12001 This means one thing…. you have something … Read more
In short: primitive types and “Primitive wrappers (Integer, Long, Short, Double, Float, Character, Byte, Boolean)” can not be altered via reference. Check http://en.wikipedia.org/wiki/Immutable_object for Details 5 solved Pass by Ref Java. Integer ins’t modified, Collection is modified, Why? [duplicate]
The if condition checking must be done using == or === operator.Because = is used to assign something.So try this if($d == 2){ $dayznum = $dayznum2; } 3 solved PHP if($d=2) not working
As others have posted, the regular expression you are looking for is: \d{4}-\d{6} The full code I would use: import re my_string = ‘Ticketing TSX – 2016-049172’ matches = re.findall(r”\d{4}-\d{6}”, my_string) print matches If, for example, the length of the second digit varies from 6 to 8 digits, you will need to update your regular … Read more
Here is your program edited to suit your needs. Everything new is explained in the comments in the code: #include <stdio.h> #include <stdlib.h> // Don’t forget # before include! int main() { char ch = NULL; //character for storing ‘q’ or ‘c’ do{ int x = 0; int y = 0; int r = 0; … Read more
You could just use a cast to an int like so: int integerNumber = (int) yourFloat; 4 solved How do I convert float to integer? [duplicate]
Nothing to stop this float fun(float a) { cout << fixed << setprecision(1); return a; } But that’s stupid code for a stupid puzzle. What does this have to do with real programming? 3 solved How to add decimal to floating point number with non-decimal value [closed]
You are trying to remove item from list, that you currently iterating on, thus, ConcurentModifiacationException occures. See here: https://stackoverflow.com/a/18448699/8851887 solved Java Integer ArrayList [closed]
To answer your last point which is interesting (the other parts of the question are best answered by a debugger), a double that is too large for an int will cast into the largest possible int; similarly for a double that is too small for an int will cast to the smallest possible int. See … Read more
Just to show you current C++ (C++20) works a bit different then wat most (older) C++ material teaches you. #include <algorithm> #include <iostream> #include <string> #include <ranges> bool is_not_four(const char digit) { return digit != ‘4’; } int main() { // such a big number iwll not fit in any of the integer types // … Read more
I suggest you not use double at all here as it is clearly confusing you. If you are going to use double, you should always round your results instead of rounding down. Additionally as 0.1 and 0.01 and 0.05 cannot be represented accurately, you should avoid using them. int iPenny = (int) Math.round((iDollarTotal – iTen … Read more
