Relational operator

In computer science, a relational operator is a programming language construct or operator that tests or defines some kind of relation between two entities. These include numerical equality (e.g., 5 = 5) and inequalities (e.g., 4 ≥ 3).

In programming languages that include a distinct boolean data type in their type system, like Pascal, Ada or Java, these operators usually evaluate to true or false, depending on whether the conditional relationship between the two operands holds or not. In languages such as C, relational operators return the integers 0 or 1, where 0 stands for false and any nonzero value stands for true.

An expression created using a relational operator forms what is known as a relational expression or a condition. Relational operators can be seen as special cases of logical predicates.

Equality

Usage

Equality is being used in many programming-language constructs and data types. It is used to test whether an element already exists in a set, or to access to a value through a key. It is used in Switch statements to dispatch the control flow to the correct branch, and during the unification process in logic programming.

9949 Brontosaurus

9949 Brontosaurus is a main belt asteroid. It orbits the Sun once every 3.61 years.

Discovered on September 22, 1990 by E. W. Elst it was given the provisional designation "1990 SK₆". It was later renamed "Brontosaurus" after Brontosaurus, a genus of dinosaur that is closely related to Apatosaurus.

GeForce 8 series

The GeForce 8 Series is the eighth generation of NVIDIA's GeForce line of graphics processing units. The third major GPU architecture developed by Nvidia, Tesla (microarchitecture) represents the company's first unified shader architecture.

GeForce 8 Series overview

All GeForce 8 Series products are based on Tesla (microarchitecture).

Max resolution

Dual Dual-link DVI Support: Able to drive two flat-panel displays up to 2560×1600 resolution. Available on select GeForce 8800 and 8600 GPUs.

One Dual-link DVI Support: Able to drive one flat-panel display up to 2560×1600 resolution. Available on select GeForce 8500 GPUs and GeForce 8400 GS cards based on the G98.

One Single-link DVI Support: Able to drive one flat-panel display up to 1920×1200 resolution. Available on select GeForce 8400 GPUs. GeForce 8400 GS cards based on the G86 only support single-link DVI.

Display capabilities

The GeForce 8 series supports 10-bit per channel display output, up from 8-bit on previous NVIDIA cards. This potentially allows higher fidelity color representation and separation on capable displays. The GeForce 8 series, like its recent predecessors, also supports Scalable Link Interface (SLI) for multiple installed cards to act as one via an SLI Bridge, so long as they are of similar architecture.
