convert double to int

Question

What is the best way to convert a double to an int? Should a cast be used?

Answer 1

The best way is to simply use Convert.ToInt32. It is fast and also rounds correctly.

Why make it more complicated?

Answer 2

Convert.ToInt32 is the best way to convert

Answer 3

Yeah, why not?

double someDouble = 12323.2;
int someInt = (int)someDouble;

Using the Convert class works well too.

int someOtherInt = Convert.ToInt32(someDouble);

Answer 4

My ways are :

 - Convert.ToInt32(double_value)
 - (int)double_value
 - Int32.Parse(double_value.ToString());
