Convert.ToInt16 Method (Single)

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

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

public static short ToInt16(
	float value
)

Parameters

value
Type: System.Single

The single-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.

ExceptionCondition
OverflowException

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

The following example attempts to convert each element in an array of Single values to a 16-bit signed integer.

float[] values = { Single.MinValue, -1.38e10f, -1023.299f, -12.98f,
                   0f, 9.113e-16f, 103.919f, 17834.191f, Single.MaxValue };
short result;

foreach (float value in values)
{
   try {
      result = Convert.ToInt16(value);
      Console.WriteLine("Converted the {0} value {1} to the {2} value {3}.",
                        value.GetType().Name, value, result.GetType().Name, result);
   }                     
   catch (OverflowException) {
      Console.WriteLine("{0} is outside the range of the Int16 type.", value);
   }   
}                                 
// The example displays the following output: 
//    -3.40282346638529E+38 is outside the range of the Int16 type. 
//    -13799999488 is outside the range of the Int16 type. 
//    Converted the Double value -1023.29901123047 to the Int16 value -1023. 
//    Converted the Double value -12.9799995422363 to the Int16 value -13. 
//    Converted the Double value 0 to the Int16 value 0. 
//    Converted the Double value 9.11299983940444E-16 to the Int16 value 0. 
//    Converted the Double value 103.918998718262 to the Int16 value 104. 
//    Converted the Double value 17834.19140625 to the Int16 value 17834. 
//    3.40282346638529E+38 is outside the range of the Int16 type.
