Description

Convert ToBoolean(Double) converts the value of the specified double-precision floating-point number to an equivalent Boolean value.

Syntax

Convert.ToBoolean(Double) has the following syntax.


public static bool ToBoolean(
  double value
)

Parameters

Convert.ToBoolean(Double) has the following parameters.

value - The double-precision floating-point number to convert.

Returns

Convert.ToBoolean(Double) method returns true if value is not zero; otherwise, false.

Example

The following example converts a Boolean to a Double and a Double to a Boolean value.


// w  ww.  j a  va  2  s .  c o  m
using System;
public class MainClass{
  public static void Main(String[] argv){  
     double doubleVal = 1.2;
     bool  boolVal;
     // Double to bool conversion cannot overflow.
     boolVal = System.Convert.ToBoolean(doubleVal);
     System.Console.WriteLine("{0} as a Boolean is: {1}.",
       doubleVal, boolVal);
     
     // bool to double conversion cannot overflow.
     doubleVal = System.Convert.ToDouble(boolVal);
     System.Console.WriteLine("{0} as a double is: {1}.",
       boolVal, doubleVal);

  }
}

The code above generates the following result.
