BitConverter.ToUInt16() expects the bytes to be reversed, i guess that's how they are stored in memory. But how can I convert it when it's not reversed, w/o modifying the array? Byte[] ba = { 0, 0, 0, 6, 0, 0 }; BitConverter.ToUInt16(ba, 2); // is 1536/0x0600, but I want 6/0x0006 ...
I realize that the value 0.00 is not a valid nonNegativeInteger, nor is it even an Integer. Unfortunately, the data is coming in that format. I don't want to throw it away if it ends with .0 but, I also don't want to change the type to Decimal and possibly have values ending in .1 coming in as valid. Is there a way my XSD can validate ...
I got a function find_nodes() with a loop inside: for (htmlNodePtr current_node=root_node ; current_node!=NULL ; current_node=current_node->next) { if (xmlHasProp(current_node,(xmlChar *)"href")) { if (xmlHasProp(current_node,(xmlChar *)attribute)) { if (strcmp(value, (char *)xmlGetProp(c...

How would i go about doing calculations with extremely large numbers in Java? i have tried long but that maxes out at 9223372036854775807, and when using an integer it does not save enough digits and therefore is not accurate enough for what i need. Is there anyway around this? ...

Setting aside the heap's capacity, are there ways to go beyond Integer.MAX_VALUE constraints in Java? Examples are: Collections limit themselves to Integer.MAX_VALUE. StringBuilder / StringBuffer limit themselves to Integer.MAX_VALUE. ...
does someone know how to have 64 bit integer on PHP? it seems like it is not by config file but rather it might be a compile time option and it depends on the platform? ...
Hi, I was recently asked this question in an interview: "How could you parse a string of the form '12345' into its integer representation 12345 without using any library functions, and regardless of language?" I thought of two answers, but the interviewer said there was a third. Here are my two solutions: Solution 1: Keep a dictiona...
I need to write a loop that does something like: if i (1..10) do thing 1 elsif i (11..20) do thing 2 elsif i (21..30) do thing 3 etc... But so far have gone down the wrong paths in terms of syntax. Any help would be much appreciated. ...
in PHP echo (int) ( (0.1+0.7) * 10 ); or in Ruby p ((0.1+0.7) *10).to_i the result is 7 instead of 8. it might be really hard to catch for such pitfalls. i think if in North America, it is less of a problem because we calculate prices up to how many cents, so $17.28 or $17.29 might be less of a problem. But in country like Chin...
I'm reading 16 bit integers from a piece of hardware over the serial port. Using python, how can I get the LSB and MSB right, and make python understand that it is a 16 bit signed integer I'm fiddling with, and not just two bytes of data? ...

In Python, I'm constantly using the following sequence to get an integer value from a byte buffer (in python this is a str). I'm getting the buffer from the struct.unpack() routine. When I unpack a 'char' using byte_buffer, = struct.unpack('c', raw_buffer) int_value = int( byte_buffer.encode('hex'), 16 ) Is there a better way? ...
Imagine two positive integers A and B. I want to combine these two into a single integer C. There can be no other integers D and E which combine to C. So combining them with the addition operator doesn't work. Eg 30 + 10 = 40 = 40 + 0 = 39 + 1 Neither does concatination work. Eg "31" + "2" = 312 = "3" + "12" This combination operation...
