WebThe Boolean data type has the same attributes and acts or behaves similarly in all programming languages. However, while all languages recognize false as 0, some languages define true as -1 rather than 1. This is the result of storing the Boolean values as an integer and using a one’s complement representation that negates all bits rather ...
