# Decimal.ToInt16 Method

Converts the value of the specified Decimal to the equivalent 16-bit signed integer.

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

## Syntax

``````'Declaration
Public Shared Function ToInt16 ( _
value As Decimal _
) As Short
``````
``````public static short ToInt16(
decimal value
)
``````

#### Return Value

Type: System.Int16
A 16-bit signed integer equivalent to value.

## Exceptions

Exception Condition
OverflowException

value is less than Int16.MinValue or greater than Int16.MaxValue.

## Examples

The following code example converts Decimal numbers to Int16 values using the ToInt16 method.

Module Example

Dim formatter As String = "{0,16}{1,19}{2,19}"

' Get the exception type name; remove the namespace prefix.
Function GetExceptionType(ByVal ex As Exception) As String

Dim exceptionType As String = ex.GetType().ToString()
Return exceptionType.Substring( _
exceptionType.LastIndexOf("."c) + 1)
End Function

' Convert the Decimal argument; catch exceptions that are thrown.

' Convert the argument to a Short value.
