Why can reinterpret_cast not convert an int to int?
According to cppreference.com the following conversion is available only since C++11: An expression of integral, enumeration, pointer, or pointer-to-member type can be converted to its own type. The resulting value is the same as the value of expression. which may not be implemented in Visual Studio 2013 RC yet.
reading two integers in one line using C#
One option would be to accept a single line of input as a string and then process it. For example: //Read line, and split it by whitespace into an array of strings string[] tokens = Console.ReadLine().Split(); //Parse element 0 int a = int.Parse(tokens[0]); //Parse element 1 int b = int.Parse(tokens[1]); One issue with this approach … Read more
Difference between Enum and IntEnum in Python
From the python Docs: Enum: Base class for creating enumerated constants. and: IntEnum: Base class for creating enumerated constants that are also subclasses of int. it says that members of an IntEnum can be compared to integers; by extension, integer enumerations of different types can also be compared to each other. look at the below … Read more
why Integer.MAX_VALUE + 1 == Integer.MIN_VALUE?
Because the integer overflows. When it overflows, the next value is Integer.MIN_VALUE. Relevant JLS If an integer addition overflows, then the result is the low-order bits of the mathematical sum as represented in some sufficiently large two’s-complement format. If overflow occurs, then the sign of the result is not the same as the sign of … Read more
Hexadecimal to Integer in Java
Why do you not use the java functionality for that: If your numbers are small (smaller than yours) you could use: Integer.parseInt(hex, 16) to convert a Hex – String into an integer. String hex = “ff” int value = Integer.parseInt(hex, 16); For big numbers like yours, use public BigInteger(String val, int radix) BigInteger value = … Read more
Convert int to CGFloat
In the past casting a CGFloat value using the () syntax has worked fine for me. CGFloat is just defined as “typedef float CGFloat;” so you go about casting it the same way you would a float: CGFloat f = (CGFloat)intVal; or, if your value is a constant: CGFloat f = 1.10;
Input model changes from Integer to String when changed
I know I’m late but I figured I’d post this answer as other people might still be searching for alternatives. You could solve this by using the AngularJS directive linking function. The code: var myMod = angular.module(‘myModule’, []); myMod.directive(‘integer’, function(){ return { require: ‘ngModel’, link: function(scope, ele, attr, ctrl){ ctrl.$parsers.unshift(function(viewValue){ return parseInt(viewValue, 10); }); } … Read more
