Convert.ToSingle Method (Byte)

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Converts the value of the specified 8-bit unsigned integer to the equivalent single-precision floating point number.

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

Syntax

'Declaration
Public Shared Function ToSingle ( _
    value As Byte _
) As Single

public static float ToSingle(
    byte value
)

Parameters

value
Type: System.Byte
An 8-bit unsigned integer.

Return Value

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

Remarks

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

Public Sub ConvertByteSingle(ByVal byteVal As Byte)
   Dim singleVal As Single

   ' Byte to float conversion will not overflow.
   singleVal = System.Convert.ToSingle(byteVal)
   outputBlock.Text &= String.Format("The byte as a single is {0}.", _
                             singleVal) & vbCrLf

   ' Single to byte conversion can overflow.
   Try
      byteVal = System.Convert.ToByte(singleVal)
      outputBlock.Text &= String.Format("The single as a byte is {0}.", _
                                byteVal) & vbCrLf
   Catch exception As System.OverflowException
      outputBlock.Text &= String.Format( _
          "Overflow in single-to-byte conversion.") & vbCrLf
   End Try
End Sub

public void ConvertByteSingle(byte byteVal)
{
   float floatVal;

   // Byte to float conversion will not overflow.
   floatVal = System.Convert.ToSingle(byteVal);
   outputBlock.Text += String.Format("The byte as a float is {0}.",
      floatVal) + "\n";

   // Float to byte conversion can overflow.
   try
   {
      byteVal = System.Convert.ToByte(floatVal);
      outputBlock.Text += String.Format("The float as a byte is {0}.",
         byteVal) + "\n";
   }
   catch (System.OverflowException)
   {
      outputBlock.Text += String.Format(
         "The float value is too large for a byte.") + "\n";
   }
}
