Explicit conversion to boolean: Boolean, CBool

The required type conversion can be carried out as follows:

explicit conversion to boolean

( type ) expression

Note: In C like languages the data type size may be different depending on compiler and architecture, we show only one standard look.

Compatible programing languages:
C++ | Visual C++ .NET | C# | Java | PHP

Explicit conversion to boolean the possible of use:

x= true; y= false;
bool b = x;          // b = true
bool b2 = x && y;    // b2 = false
bool b3 = (bool) 0;  // b3 = false

 Boolean (expr)

Used keywords: boolean

Compatible programing languages:
JavaScript | Object Pascal | Free Pascal | Pascal

Explicit conversion to boolean the possible of use:

x:= true; y:= false;
b:= x;          // b = true
b2:= x and y;    // b2 = false
b3:= Boolean( 0);  // b3 = false

 CBool (expr)

Used keywords: cbool

Compatible programing languages:
Visual Basic .NET | FreeBASIC

Explicit conversion to boolean the possible of use:

x= true
 y= false
Dim b As boolean= x          ' b = true
Dim b2 As boolean= x and y    ' b2 = false
Dim b3 As boolean= CBool( 0)  ' b3 = false
