=={{header|D}}==
In D, there are constants true and false to represent their respective values.
Implicit conversions are listed below:
* any integer type, where 0 converts to false, and any other value converts to true
* any floating point type, where again, 0 gives false and everything else gives true
* any enumeration type, again 0 gives false, anything else true
* any pointer type, where the null pointer gives false and any other pointer gives true
* any reference type, where the null reference gives false and any other reference gives true
* any user-defined type with an implicit conversion operator either to bool or to a built-in type which itself can be converted to bool
