An INT will always be 4 bytes no matter what length is specified. TINYINT = 1 byte (8 bit) SMALLINT = 2 bytes (16 bit) MEDIUMINT = 3 bytes (24 bit) INT = 4 bytes (32 bit) BIGINT = 8 bytes (64 bit). The length just specifies how many characters to pad when selecting data … Read more
Take a look at this: >>> a = 256 >>> b = 256 >>> id(a) 9987148 >>> id(b) 9987148 >>> a = 257 >>> b = 257 >>> id(a) 11662816 >>> id(b) 11662828 Here’s what I found in the Python 2 documentation, “Plain Integer Objects” (It’s the same for Python 3): The current implementation keeps … Read more
Converting Int to String: let x : Int = 42 var myString = String(x) And the other way around – converting String to Int: let myString : String = “42” let x: Int? = myString.toInt() if (x != nil) { // Successfully converted String to Int } Or if you’re using Swift 2 or 3: … Read more
Use the strconv package’s Itoa function. For example: package main import ( “strconv” “fmt” ) func main() { t := strconv.Itoa(123) fmt.Println(t) } You can concat strings simply by +‘ing them, or by using the Join function of the strings package.
Try this: int x = Int32.Parse(TextBoxD1.Text); or better yet: int x = 0; Int32.TryParse(TextBoxD1.Text, out x); Also, since Int32.TryParse returns a bool you can use its return value to make decisions about the results of the parsing attempt: int x = 0; if (Int32.TryParse(TextBoxD1.Text, out x)) { // you know that the parsing attempt // … Read more
From Wikipedia: According to the 1999 ISO C standard (C99), size_t is an unsigned integer type of at least 16 bit (see sections 7.17 and 7.18.3). size_tis an unsigned data type defined by several C/C++ standards, e.g. the C99 ISO/IEC 9899 standard, that is defined in stddef.h.1 It can be further imported by inclusion of … Read more
C++11 introduces std::stoi (and variants for each numeric type) and std::to_string, the counterparts of the C atoi and itoa but expressed in term of std::string. #include <string> std::string s = std::to_string(42); is therefore the shortest way I can think of. You can even omit naming the type, using the auto keyword: auto s = std::to_string(42); … Read more
Just cast the enum, e.g. int something = (int) Question.Role; The above will work for the vast majority of enums you see in the wild, as the default underlying type for an enum is int. However, as cecilphillip points out, enums can have different underlying types. If an enum is declared as a uint, long, … Read more
