# 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)

## Syntax

``````Public Shared Function ToInt32 ( _
value As Double _
) As Integer
``````
``````public static int ToInt32(
double value
)
``````

#### 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.

## Exceptions

Exception Condition
OverflowException

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

## Examples

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

``````Public Sub ConvertDoubleInt(ByVal doubleVal As Double)

Dim intVal As Integer = 0
' Double to Integer conversion can overflow.
Try
intVal = System.Convert.ToInt32(doubleVal)
outputBlock.Text &= String.Format("{0} as an Integer is: {1}", _
doubleVal, intVal) & vbCrLf
Catch exception As System.OverflowException
outputBlock.Text &= String.Format( _
"Overflow in Double-to-Byte conversion.") & vbCrLf
End Try

' Integer to Double conversion cannot overflow.
doubleVal = System.Convert.ToDouble(intVal)
outputBlock.Text &= String.Format("{0} as a Double is: {1}", _
intVal, doubleVal) & vbCrLf
End Sub
``````
``````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";
}
``````
