Boolean
Boolean refers to a system of processes which are logical or algebraic in nature, which was developed by a person named George Boole. Basically, "Boolean" expressions represent logical reasoning or operations.
A common example of boolean logic in action are search engines. When conducting an advanced
search of terms you may see fields like "AND," "OR" and "NOT." These
are basically logical processes that refine your search, including or excluding certain terms. Another
common example of boolean expressions are the simple "true or false" and "yes or no"
answers to fields.
OpenOffice.org can work with boolean expressions in several different ways. Calc
can process boolean values in its functions.
Base can include boolean arguments in its
database tables, forms and queries. Math can create and display
boolean relationships among variables.
Using Boolean Expressions
The following screencasts demonstrate how to use boolean expressions:
- Format numbers in cells into boolean values and back
- Enter the boolean or logical expression "a and b"
- Enter the boolean or logical expression "a or b"
- Enter the boolean expression "not a"
- Set a database table field type to boolean (coming soon)
