ToInt16 Method (Double)

# Convert.ToInt16 Method (Double)

.NET Framework (current version)

Converts the value of the specified double-precision floating-point number to an equivalent 16-bit signed integer.

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

## Syntax

```public static short ToInt16(
double value
)
```

#### Parameters

value
Type: System.Double

The double-precision floating-point number to convert.

#### Return Value

Type: System.Int16

value, 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.

## Exceptions

Exception Condition
OverflowException

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

## Examples

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.

```double[] values = { Double.MinValue, -1.38e10, -1023.299, -12.98,
0, 9.113e-16, 103.919, 17834.191, Double.MaxValue };
short result;

foreach (double value in values)
{
try {
result = Convert.ToInt16(value);
Console.WriteLine("Converted {0} to {1}.", value, result);
}
catch (OverflowException)
{
Console.WriteLine("{0} is outside the range of the Int16 type.", value);
}
}
//       -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.
```
