How do you convert a double to an int?

Question

double one = tips[0];

double two = tips[1];
double three = tips[2];
double four = tips[3];
double five = tips[4];
double six = tips[5];
double seven = tips[6];

int average = one, two, three, four, five, six, seven;

The compiler is saying I need to convert a double to int but I don't know how. This is all I find on the internet.

public static double ToDouble(
    int value
)

But I don't understand it and don't know how to put it in my code to make it work.

`int average = one, two, three, four, five, six, seven;` You know this is completely invalid, right? — Jonathon Reinhart, Sep 17 '13 at 07:06
I need to put one, two .... together to compute average could I do "double average = (one + two + three + four + five + six + seven) / 7;" — user2676862, Sep 17 '13 at 07:10

You may cast it:

double d = 0;
int i = (int)d;

or convert it:

double d = 0;
int i = Convert.ToInt32(d);

You can use (int) to cast a double to an int, however the average should be double. For calculating the average, you should use LINQ:

double average = tips.Average();
//or
int average = (int) tips.Average();

I cant figure out how to get it to a int but it just looks easier to keep it a double – user2676862 Sep 17 '13 at 07:07
@user2676862 that's the job of the `compiler`, we just provide the correct `syntax`. – King King Sep 17 '13 at 07:08

To actually compute your average, use LINQ! Namely Enumerable.Average(IEnumerable<double>)

double[] tips = new[] { 1.4, 2.6, 3.2 };

double average = tips.Average();

Convert.ToInt32();

or

Int.parse();

Convert yes, parse no, parse accepts string not double, so you need convert double to string, then string to int, not good idea. – Kamil Budziewski Sep 17 '13 at 07:04

You could use the static Convert class.

The result would be:

var myInt = Convert.ToInt32(myDouble);

try:

int varInt = Convert.ToInt32(varDouble);

and also check this other answer: convert double to int
