long-integer

I have problem writing an unsigned 4 bytes int in java. Either writing a long value in java has different result on 64 bit MacOS and 32 bit Linux (Ubuntu) OR Writing to network a 4 byte unsigned int has a problem. The following call works perfectly on my local OSX writeUInt32(999999,outputstream) Reading it back gives me 999999 However when the application is deployed to a network writing a long value results in some other random number (I assume the endian has been switched?) and reading it gives me some other large number. ---------- The complete method stack is as below---------------

I have a Python version 3.3.0 and I am not sure why it does not let me do long for b and m here... I tried to look up the answers on here and but nothing helped...thanks im getting an error saying NameError: global name 'long' is not defined power = long(b) % long(m) In Python 3.x, use int instead of long . From What’s New In Python 3.0, Integers : PEP 237 : Essentially, long renamed to int . That is, there is only one built-in integral type, named int ; but it behaves mostly like the old long type. 来源： https://stackoverflow.com/questions/14904814/nameerror-global-name-long-is-not-defined

I've been programming in C++ for quite a while now and I am pretty familiar with most of the stuff. One thing that I've never understood though is the 'long' data type. I googled it but I still don't know what it is for. I've found pages that say it is the same size and has the same range as an int. So what would be the point in using it? I found another stack overflow question regarding this here: Difference between long and int data types And it seems that the only difference between the two is that sometimes the size is different on different systems. Does that mean that an application that

I am trying to encode a simple String "test" back and forth. public static String encode(Key publicKey, String data) throws NoSuchAlgorithmException, NoSuchPaddingException, InvalidKeyException, IllegalBlockSizeException, BadPaddingException { byte[] byteData = data.getBytes(); // convert string to byte array Cipher cipher = Cipher.getInstance(ALGORITHM); // create conversion processing object cipher.init(Cipher.ENCRYPT_MODE, publicKey); // initialize object's mode and key byte[] encryptedByteData = cipher.doFinal(byteData); // use object for encryption return new String(encryptedByteData); //

How could i convert data from string to long in C#? I have data String strValue[i] ="1100.25"; now i want it in long l1; Convert.ToInt64("1100.25") Method signature from MSDN: public static long ToInt64( string value ) If you want to get the integer part of that number you must first convert it to a floating number then cast to long. long l1 = (long)Convert.ToDouble("1100.25"); You can use Math class to round up the number as you like, or just truncate... Math.Round Math.Ceil http://msdn.microsoft.com/en-us/library/system.convert.aspx l1 = Convert.ToInt64(strValue) Though the example you gave

A similar question Long in Float, why? here does not answer what I am searching for. C# standard allows implicit conversion from long to float. But any long greater than 2^24 when represented as a float is bound to lose its 'value'. C# standard clearly states that long to float conversion may lose 'precision' but will never lose 'magnitude'. My Questions are In reference to integral types what is meant by 'precision' and 'magnitude'. Isn't number n totally different from number n+1 unlike real numbers where 3.333333 and 3.333329 may be considered close enough for a calculation (i.e. depending
