cast to void *' from smaller integer type 'int

Even 1.99 should result in 1. The size of pointers in general are not guaranteed to be anything.A char* could be a different size than an int*.A void* is guaranteed to be castable to other pointer types (AFAICR), so it follows that a void* should be no smaller than the largest of any other type of pointer's significant bits. (See also in cppreference integeger types for C99). You can also do explicit type casting. Character.getNumericValue () Integer.parseInt () //in pair with String.valueOf ()) Subtracting '0' //works for integer numeric values only. Delegates are declared similarly to function pointers: Is it ok to cast enum to int - CodeProject TXT for details. 1. Click to see the query in the CodeQL repository. actually no, as int my be a smaller type than a pointer ;-) But, of course with int64_t it works fine. Convert Byte to Int Using the Byte Wrapper Class and Casting in Java. It is because the int data type is comparatively bigger than the char data type in C. Type conversion is a process in which the data type is automatically converted into another data type. static_cast in C++ | Type Casting operators - GeeksforGeeks If you cast from bool to int, the result will be 0 (false) or 1 (true). Casting some values can result in unexpected behavior. If you want to not add an extra compilation flag due to the fact that you might be upcasting an int to a void* accidentally somewhere else, you can use the following snippet to force a cast from an int to a void* where you are sure you want it to happen and then the compiler won't bug you about the cast: On a 64-bit Windows computer, 'long' is a 32-bit type, and all pointers are 64-bit types. The code actually worked fine because the integer values in use are all small. C++ supports four types of casting: 1. So, to convert an int to double using widening casting, you can just assign a value of int to double. Here, the int type variable is automatically converted into double. Pd = Pa; Similarly, Pc may be type cast to type int and assigned the value Pa. 1. The static_cast operator cannot cast away the const . Casting a type with a large range of a type with a smaller range is known as narrowing a type. there is no automatic conversion defined from double to byte. It's quick & easy. It does not check if the pointer type and data pointed by the pointer is same or not. XCode编译报错 Cast from pointer to smaller type 'int' loses information由于使用了强转将void*转为int，而在XCode上使用的为x64的编译，X64下的void*地址为8字节，而int为4字节，强转时会导致越界，故出现此错误。 void* pParam = 1;所以应将 int index = (int)pParam改为long i.
