I have this PHP code: $entityElementCount = (-($highScore-$totalKeywordCount))/0.29; What i want to know is, how to check whether $entityElementCount is a whole number (2, 6, ...) or partial (2.33, 6.2, ...). Thank you! ...
In python, is there a command similar to len() which works on integers? Thanks ...
I need to store some integer values as the contents of an array. But when i try to do so, it throws a warning, passing argument 1 of 'addObject' makes pointer from integer without a cast. And obviously the value is not stored in the array. Here's thecode. NSUInteger i; for (i=0;i<5;i++){ [array addObject:i];} ...
I’m trying to determine the relationship of a given compiler’s integer types’ sizes using the preprocessor. My requirement is that I have two types, one of which is unsigned, and one of which is a signed type capable of storing every positive number that said unsigned type can store. i.e. I have to ensure that my ll_ssize type can store ...
It seems as though I'm having problems accessing Integer.parseInt in comp. I can access it normally like this: user=> (Integer/parseInt "123") 123 But if I put it in comp, I get an error: user=> (def vect-to-int (comp Integer/parseInt (partial apply str))) java.lang.Exception: Unable to find static field: parseInt in class java.lang...
Hello All, I'm trying to do something common enough: Parse user input in a shell script. If the user provided a valid integer, the script does one thing, and if not valid, it does something else. Trouble is, I haven't found an easy (and reasonably elegant) way of doing this - I don't want to have to pick it apart char by char. I know t...
Possible Duplicate: how to perform bitwise operation on floating point numbers Hello, everyone! Background: I know that it is possible to apply bitwise operation on graphics (for example XOR).

I have an array of about 10-100k ints that I need to store (as compressed as possible), and retrieve back to the complete array the fastest way possible. What is the best way to handle this type of thing in a language like c#. ...
If I have an integer like this in several places in my code... int my_secret = 42; ... is it possible to make it more difficult to find that integer in the compiled program? I've seen this done with strings, for example by shifting each letter by x characters and then un-shifting them at runtime, but I doubt this technique would work ...

It's not possible to do something like fputs(4, fptOut); because fputs doesn't like integers. How can I work around this? Doing fputs("4", fptOut); is not an option because I'm working with a counter value. ...
I just wonder how to write a number that has to be expressed as string. For instance: if (SelectedItem.Value == 0.ToString()) ... or if (SelectedItem.Value == "0") ... or public const string ZeroNumber = "0"; if (SelectedItem.Value == _zeroNumber) ... or if (Int.Parse(SelectedItem.Value) == 0) ...

How can I convert an RGB integer to the corresponding RGB tuple (R,G,B)? Seems simple enough, but I can't find anything on google. I know that for every RGB (r,g,b) you have the integer n = r256^2 + g256 + b, how can I solve the reverse in Python, IE given an n, I need the r,g,b values. ...
I had to write the following function to fail gracefully when trying to parse a string to an integer. I would imagine Python has something built in to do this, but I can't find it. If not, is there a more Pythonic way of doing this that doesn't require a separate function? def try_parse_int(s, base=10, val=None): try: return int(s...

This has to do with a question I read yesterday: http://stackoverflow.com/questions/2274428/how-to-determine-how-many-bytes-an-integer-needs Anyway, the part that I have a question about is this: I'm looking for the most efficient way to calculate the minimum number of bytes needed to store an integer without losing precision. ...
I have values that are 64-bit unsigned ints, and I need to store them in mongodb, which has no unsigned int type. I see three main possibilities for storing them in other field types, and converting on going in and out: Using a signed int is probably easiest and most space efficient, but has the disadvantage that they're not human reada...
