Convert.ToInt32 Method (Double)

Converts the value of the specified double-precision floating point number to an equivalent 32-bit signed integer.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

public static int ToInt32(
	double value
)

Parameters

value
Type: System.Double
A double-precision floating point number.

Return Value

Type: System.Int32
value rounded to the nearest 32-bit signed integer. If value is halfway between two whole numbers, the even number is returned; that is, 4.5 is converted to 4, and 5.5 is converted to 6.

ExceptionCondition
OverflowException

value is greater than Int32.MaxValue or less than Int32.MinValue.

The following code sample illustrates the conversion of a Double value to an Int32, using ToInt32.


public void ConvertDoubleInt(double doubleVal)
{

   int intVal = 0;
   // Double to int conversion can overflow.
   try
   {
      intVal = System.Convert.ToInt32(doubleVal);
      outputBlock.Text += String.Format("{0} as an int is: {1}",
         doubleVal, intVal) + "\n";
   }
   catch (System.OverflowException)
   {
      outputBlock.Text += String.Format(
         "Overflow in double-to-int conversion.") + "\n";
   }

   // Int to double conversion cannot overflow.
   doubleVal = System.Convert.ToDouble(intVal);
   outputBlock.Text += String.Format("{0} as a double is: {1}",
      intVal, doubleVal) + "\n";
}
