With methods test1() and test2(), I get a Type Mismatch Error: Cannot convert from null to int, which is correct; but why am I not getting the same in method test3()? How does Java evaluates the conditional expression differently in that case? (obviusly, a NullPointerException will rise in runtime). Is it a missing error?

Hello!
Does anyone know of a class/library/etc. that can simulate 32 bit unsigned integers on a 32 bit platform in PHP?
I'm porting a C lib into PHP and it uses a lot of integers that are greater than the maximum for 32 bit signed int.
I have just tried implementing a class where numerous length/count properties, etc. are uint instead of int. However, while doing so I noticed that it's actually painful to do so, like as if no one actually wants to do that.
Nearly everything that hands out an integral type returns an int, therefore requiring casts in several points. I wanted to…
Maybe there is a very logic explanation for this, but I just can't seem to understand why the seeds 0 and 2,147,483,647 produce the same "random" sequence, using .NET's Random Class (System).
Quick code example:
ushort len = 8;
Random r0 = new Random(0), r1 = new Random(1), r2 = new Random(int.MaxValue); //2,147,483,647
byte[] b0 = new…
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…
I have a long int variable that I need to convert to a signed 32bit hexadecimal string (8 characters) (char array) without the "0x" at the start?
How would I go about doing this?
Thanks.
Both queries below translates to the same number
SELECT CONVERT(bigint,CONVERT(datetime,'2009-06-15 15:00:00'))
SELECT CAST(CONVERT(datetime,'2009-06-15 23:01:00') as bigint)
Result
39978
39978
The generated number will be different only if the days are different. There is any way to convert the DateTime to a more precise…
Hello.
I have an array with integers of values from 0 to 100. I wish to remove integers that are less than number X and keep the ones that are equal or greater than number X.
I am using PHP.
Thanks!
I'm trying to write a program to calculate a cross product of two vectors (input is of "real" type, so for example [1.3 3.4 1,5]). But I keep getting numerous errors:
program Q3CW
implicit none
REAL :: matA(3), matB(3)
REAL :: A11, A12, A13
REAL :: B11, B12, B13
real :: productc(3), answer(3)

if i wanted to reference an int from another class how would i go about doing that???

I have 1,2,3,4,5,6,7,8,9 stored as nvarchar inside Level in my db.
I then have a dropdownlist with values 1,2,3,4,5,6,7,8,9. When a user makes a selection (i.e 1) (Level.SelectedValue.ToString). This builds an sql query via a param like this:

Hey everybody,
I'm a total C# newb with a light (first year CS) background in Python. I wrote a console program in Python for doing marathon pace running calculations and I'm trying to figure out the syntax for this in C# using Visual Studio 2010. Here's a chunk…
I need to calculate modulus with large number like :
<?php
$largenum = 95635000009453274121700;
echo $largenum % 97;
?>
It's not working... beacause $largenum is too big for an int in PHP.
Any idea how to do this ?
Hi,
I am trying to divide integers but get 0 as result. I just do not understand what i am doing wrong. I am using only int's in this example but get the same result testing with float or double.
The code i use is:
int wrongAnswers = askedQuestions -…
Which way is better for removing float decimals places or is there a more efficient way?
Rounding is not important, i am interested in displaying the number

I have:
L1 = ['11', '10', '13', '12', '15', '14', '1', '3', '2', '5', '4', '7', '6', '9', '8']
this is a list of strings, right?
I need to make it a list of integers as follows:
L2 = [11, 10, 13, 12, 15, 14, 1, 3, 2, 5, 4, 7, 6, 9, 8]
finally I…
Is there a better shorter way than iterating over the array?
int[] arr = new int[] { 1, 2, 3 };
int sum = 0;
for (int i = 0; i < arr.Length; i++)
{
sum += arr[i];
}
clarification:
Better primary means cleaner code but hints on…
There is a function in the AES algorithm, to multiply a byte by 2 in Galois Field.
This is the function given in a website

return (byte)(int)(b <<1);

Let's say that the environment is x86.
How do compilers compile the "" operator on 32 bit integers.
Logically, I mean. Without any knowledge of Assembly.
Let's say that the high level language code is:

x = 123;
y = 456;
