.NET Framework (current version)
Converts the value of the specified double-precision floating-point number to an equivalent 16-bit signed integer.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- value
-
Type:
System.Double
The double-precision floating-point number to convert.
Return Value
Type: System.Int16value, rounded to the nearest 16-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.
| Exception | Condition |
|---|---|
| OverflowException | value is greater than Int16.MaxValue or less than Int16.MinValue. |
The following example converts each element in an array of Double values to a 16-bit signed integer. The example illustrates that any fractional part of a Double value is rounded before performing the conversion.
Dim values() As Double = { Double.MinValue, -1.38e10, -1023.299, -12.98, _ 0, 9.113e-16, 103.919, 17834.191, Double.MaxValue } Dim result As Short For Each value As Double In values Try result = Convert.ToInt16(value) Console.WriteLine("Converted {0} to {1}.", value, result) Catch e As OverflowException Console.WriteLine("{0} is outside the range of the Int16 type.", value) End Try Next ' -1.79769313486232E+308 is outside the range of the Int16 type. ' -13800000000 is outside the range of the Int16 type. ' Converted -1023.299 to -1023. ' Converted -12.98 to -13. ' Converted 0 to 0. ' Converted 9.113E-16 to 0. ' Converted 103.919 to 104. ' Converted 17834.191 to 17834. ' 1.79769313486232E+308 is outside the range of the Int16 type.
