No, there is and has never been an explicit built in option for conversion of Int to Bool, see the language reference for Bool for details. There exists, still, however, an initializer by NSNumber. The difference is that implicit bridging between Swift numeric type and NSNumber has been removed in Swift 3 (which previously allowed …
In case of casting a float/double value to int, you generally loose the fractional part due to integer truncation. This is quite different from rounding as we would usually expect, so for instance 2.8 ends up as 2 with integer truncation, just as 2.1 would end up as 2. Update: Another source of potential (gross) …
C++ defines no such type as uint. This must be “your” type, i.e. a type defined in your code or some third party library. One can guess that it is the same as unsigned int. Could be unsigned long int though or something else. Anyway, you have to check it yourself. It is a matter …
You are never assigning the values inside the test2 array. You have declared it but all the values will be 0. Here’s how you could assign a random integer in the specified interval for each element of the array: int Min = 0; int Max = 20; // this declares an integer array with 5 …
Use the function string_of_int (see the documentation for Pervasives, the module containing the functions that are automatically made available in the top level namespace to al OCaml programs).
Well, here’s a quick explanation: An int and float usually take up “one-word” in memory. Today, with the shift to 64bit systems this may mean that your word is 64 bits, or 8 bytes, allowing the representation of a huge span of numbers. Or, it could still be a 32bit system meaning each word in …
My fix has been to define my own constants as I couldn’t find any in os or syscall: const ( OS_READ = 04 OS_WRITE = 02 OS_EX = 01 OS_USER_SHIFT = 6 OS_GROUP_SHIFT = 3 OS_OTH_SHIFT = 0 OS_USER_R = OS_READ<<OS_USER_SHIFT OS_USER_W = OS_WRITE<<OS_USER_SHIFT OS_USER_X = OS_EX<<OS_USER_SHIFT OS_USER_RW = OS_USER_R | OS_USER_W OS_USER_RWX = OS_USER_RW …
C++ and C# are different languages. They have different rules for handling type promotion in the event of comparisons. In C++ and C, they’re usually compared as if they were both unsigned. This is called “unsigned preserving”. C++ and C compilers traditionally use “unsigned preserving” and the use of this is specified in the C++ …
