	double value
)

Parameters

value

The following code sample illustrates the conversion of a Double to Single, using ToSingle.


public void CovertDoubleFloat(double doubleVal)
{
   float floatVal = 0;

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

   // Conversion from float to double cannot overflow.
   doubleVal = System.Convert.ToDouble(floatVal);
   outputBlock.Text += String.Format("{0} as a double is: {1}",
      floatVal, doubleVal) + "\n";
}
