Convert.ToByte Method (Single)
Microsoft Silverlight will reach end of support after October 2021. Learn more.
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)
Syntax
'Declaration
Public Shared Function ToByte ( _
value As Single _
) As Byte
public static byte ToByte(
float value
)
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.
Exceptions
Exception | Condition |
---|---|
OverflowException | value is greater than Byte.MaxValue or less than Byte.MinValue. |
Examples
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
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";
}
}
