[Visual Basic]
Public Shared Function ToInt16( _
   ByVal value As Decimal _
) As Short
[C#]
public static short ToInt16(
 decimal value
);
[C++]
public: static short ToInt16(
 Decimal value
);
[JScript]
public static function ToInt16(
   value : Decimal
) : Int16;

Parameters

value
A Decimal value.

Return Value

A 16-bit signed integer equivalent to value.

Exceptions

Exception Type Condition
