Sannleiksverðmæti

Sannleiksverðmæti is an Icelandic term that translates to "truth value" in English. It is a fundamental concept in logic and computer science, referring to the classification of a proposition or statement as either true or false. Every declarative sentence that can be evaluated as factually correct or incorrect possesses a sannleiksverðmæti. This binary nature is crucial for logical operations and reasoning.

In formal logic, propositions are the building blocks of arguments. Each proposition is assigned a sannleiksverðmæti, which is either T (true) or F (false). Logical connectives like "and," "or," and "not" operate on these sannleiksverðmæti to determine the truth value of more complex statements. For instance, the conjunction of two propositions ("p and q") is only true if both individual propositions (p and q) are true.

The concept extends to computer science, particularly in Boolean logic and programming. Variables and expressions often evaluate to a sannleiksverðmæti, which then dictates the flow of control in a program. Conditional statements, loops, and other logical structures rely on evaluating these truth values to execute specific code blocks. Understanding sannleiksverðmæti is therefore essential for both formal logical analysis and practical programming.
