Convert::ToByte Method (Single)


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)

static unsigned char ToByte(
	float value


Type: System::Single

A single-precision floating-point number.

Return Value

Type: System::Byte

value, rounded to the nearest 8-bit unsigned 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.

Exception Condition

value is greater than Byte::MaxValue or less than Byte::MinValue.

The following example converts a Single value to a Byte.

   void ConvertByteSingle( Byte byteVal )
      float floatVal;

      // Byte to float conversion will not overflow.
      floatVal = System::Convert::ToSingle( byteVal );
      System::Console::WriteLine( "The Byte as a float is {0}.",
         floatVal );

      // Float to Byte conversion can overflow.
         byteVal = System::Convert::ToByte( floatVal );
         System::Console::WriteLine( "The float as a Byte is {0}.",
         byteVal );
      catch ( System::OverflowException^ ) 
            "The float value is too large for a Byte." );
