Convert.ToSingle Method (Int64)

Converts the value of the specified 64-bit signed integer to an equivalent single-precision floating point number.

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

public static float ToSingle(
	long value


Type: System.Int64
A 64-bit signed integer.

Return Value

Type: System.Single
A single-precision floating point number equivalent to the value of value.

The following code sample illustrates the conversion of an Int64 to Single, using ToSingle. Note that large Int64 values can cause OverflowException to be thrown.

public void ConvertLongFloat(long longVal)
   float floatVal;

   // A conversion from Long to float cannot overflow.
   floatVal = System.Convert.ToSingle(longVal);
   outputBlock.Text += String.Format("{0} as a float is {1}",
         longVal, floatVal) + "\n";

   // A conversion from float to long can overflow.
      longVal = System.Convert.ToInt64(floatVal);
      outputBlock.Text += String.Format("{0} as a long is {1}",
         floatVal, longVal) + "\n";
   catch (System.OverflowException)
      outputBlock.Text += String.Format(
         "Overflow in float-to-long conversion.") + "\n";
