ToByte Method (Single)

Convert.ToByte Method (Single)

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

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

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

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

Parameters

value
Type: System.Single
A single-precision floating point number.

Return Value

Type: System.Byte
value rounded to the nearest 8-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 Byte.MaxValue or less than Byte.MinValue.

The following code sample illustrates the use of ToByte, converting a Single (float) value to a Byte :


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
