division?

if i divide 10 / 4 ill get a 2 when i should get a 2,5..in vb if we did 10 \ 4 we'd get a 2,5 and if we did 10 / 4 we'd get a 2...but how do i do the \ in C#? i noticed the MOD operator doesnt exist in C# too =\

i saw on msdn and it says the / is overloaded...but how da hell do i do to make that when i want it to have decimal and not decimal then?

When integers are used with arithmetic operators, an integer is returned and any remainder is discarded. When floating-point numbers are used with arithmetic expressions, a floating-point number is returned.

Code:

---

static void Main(string[] args)
{
        double returnVal = 0;
        returnVal = (10 / 4f);
        Console.WriteLine(returnVal);
}

---

Also, the mod operator is: %

PHP Code:

---

            int iMax = nTab.Width / IMAGE_WIDTH;
            MessageBox.Show(iMax.ToString()); 


---

what do i do?

You are assigned the result to an integer. Do you want a whole number or floating-point #?

hmm i dont get what u mean...nTab = 777 and IMAGE_WIDTH is 115...i want it to return 6,7565217391304347826086956521739

Code:

---

  double dMax = (nTab.Width / IMAGE_WIDTH);

---

ah it has to be a double?

not working dude :(

Yep, integral numbers discard any decimal values.

what is the return?

ah so 1st i must convert all the values to double right?

is 6 lol

You must be working with integer types. Assign them to double variables.

yea worked now :

PHP Code:

---

            double val1 = nTab.Width; double val2 = IMAGE_WIDTH;
            double iMax = (val1 / val2);
            MessageBox.Show(iMax.ToString());

isnt there a way that i can do like in vb.net CTYPE(converttype) CTYPE(nTab.Width,wished type) ?

You will have to cast the variable to the desired type.
( Type Goes Here.. )

Code:

---

    double myDouble = (double) nTab.Width;

---

ah casting is the equivalent to the VB Ctype()?

That's what CType() does..It converts a variables type to a different type.

yea but i didnt know casting was the same thing lolol

Here's another way just for reference:

Code:

---

{
        int width = 777, height = 100;
        float result = ((float)width / (float)height);
        Console.WriteLine(result);
}

what the difference between float,double and integer? and longs? and int16 int32 int64?

There are eight integral types you can use to represent whole or integer numbers:
sbyte, byte, short, ushort, int, uint, long, ulong

As you can see, each type has a signed and unsigned version of the type.

Then we have floating-point types. There are three floating-point types you can use to represent floating-point numbers:
floag, double, decimal

These allow for n # of places after the decimal (precision).

thats the theory..but why do ppl use ints and not shorts? or uints? or sbyts?

Well, each types takes up a different amount of memory when stored on the stack. Don't u agree its a waste to store the number 5 into a long when a byte type would suffice?

hmm...int suports how much memory? 32? and this means what? it can handle up to 32 chars?

32 bits, which is equivalent = -2,147,483,647 to 2,147,483,647 (signed)

isnt there a table around there to see from where to where go that values lol?

Yeah, I'm actually getting ready to leave for a costume party, so do a search and I'm sure you'll find all your looking for.

yea i believe so tks
