Floating point - Wikipedia, the free encyclopedia
In computing, floating point describes a system for numerical representation in which a string of digits (or bits) represents a rational number. The term floating point refers to the fact that the...

Floating-point operations involve floating-point numbers and typically take longer to execute than simple binary integer operations. For this reason, most embedded applications avoid wide-spread usage of floating-point math in favor of faster, smaller integer operations.

First we will describe how floating point numbers are represented. Java uses a subset of the IEEE 754 binary floating point standard to represent floating point numbers and define the results of arithmetic operations.

Floating-point arithmetic is considered an esoteric subject by many people. This is rather surprising because floating-point is ubiquitous in ... When floating-point operations are done with a guard digit, they are not as accurate as if they were computed exactly then rounded to the nearest floating-point number.

(redirected from trillion floating point operations per second) ... In computing, jargon for 1 trillion floating point operations (computations) per second. In 2005, the IBM-built ‘BlueGene/L’ broke its own record as the world's fastest supercomputer by performing 280 teraflops per second.

As a result, floating point operations may result in rounding errors, yielding a result that is close to -- but not equal to -- the result you might expect. For example, the simple calculation below results in 2.600000000000001, rather than 2.6:

Though unofficial news leaked this morning, this afternoon, independent sources are acknowledging a new fact: A computer made with IBM Cell and AMD Opteron processors can process a thousand trillion operations per second. ... and at this point, its competition is starting to look like 499 coyotes left in the dust.

Floating point hardware was standard throughout the 7090/94 family. The 7090 had single precision (36-bit) floating point operations while the 7094/7094 II machines also provided double precision (72-bit) floating point instructions.
