C# Convert ToByte(Single)

Description

Convert ToByte(Single) converts the value of the specified single-precision floating-point number to an equivalent 8-bit unsigned integer.

Syntax

Convert.ToByte(Single) has the following syntax.


public static byte ToByte(
  float value
)

Parameters

Convert.ToByte(Single) has the following parameters.

value - A single-precision floating-point number.

Returns

Convert.ToByte(Single) method returns 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.

Example

The following example converts a Single value to a Byte.


/* w w  w  . ja v a 2 s.  c  o m*/
using System;
public class MainClass{
  public static void Main(String[] argv){  
    byte byteVal = 0;
    float floatVal = 1.2F;
    
    // 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.");
    }

  }
}

The code above generates the following result.
