There are two problems: Int is a 64-bit integer on 64-bit platforms, your input data has only 32-bit. Int uses a little-endian representation on all current Swift platforms, your input is big-endian. That being said the following would work: let array : [UInt8] = [0, 0, 0, 0x0E] var value : UInt32 = 0 let … Read more
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) … Read more
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 … Read more
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 … Read more
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 … Read more
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 … Read more
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++ … Read more
There is a toInteger function you can use.
No, TryParse returns true or false to indicate success. The value of the out parameter is used for the parsed value, or 0 on failure. So: int value; if (Int32.TryParse(someText, out value)) { // Parse successful. value can be any integer } else { // Parse failed. value will be 0. } So if you … Read more
