What's the difference between boolean and false?

Boolean


Definition:

Example Sentences:

  • (1) It also can do user defined searches using Boolean logic.
  • (2) Understanding patterns that are associated with survival or death may require alternative mathematic approaches, such as group and set theory manipulated by principles of Boolean algebra.

  • (18) A computer program using these Boolean logic functions calculates: Light and dark adaptation responses; Color matching and spectral coordinate functions; Chromatic adaptation and color shift responses; and dynamic neural responses.
  • (19) It comprises two complementary approaches: a logical analysis in terms of discrete (boolean) variables and functions and a more classical analysis in terms of differential equations.
  • (20) Search software characteristics that affect ease of searching and quality of results also need to be examined, e.g., the ability to truncate search terms and the order of precedence in which Boolean operators are evaluated.
