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)

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 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.

ExceptionCondition
OverflowException

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

The following example converts a Single value to a Byte.


		public 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.
			try {
				byteVal = System.Convert.ToByte(floatVal);
				System.Console.WriteLine("The float as a byte is {0}.",
					byteVal);
			}
			catch (System.OverflowException) {
				System.Console.WriteLine(
					"The float value is too large for a byte.");
			}
		}
