floating
In computing, floating-point arithmetic (FP) is arithmetic using formulaic representation of real numbers as an approximation to support a trade-off between range and precision. For this reason, floating-point computation is often found in systems which include very small and very large real numbers, which require fast processing times. A number is, in general, represented approximately to a fixed number of significant digits (the significand) and scaled using an exponent in some fixed base; the base for the scaling is normally two, ten, or sixteen. A number that can be represented exactly is of the following form:
significand
×
base
exponent
,
{\displaystyle {\text{significand}}\times {\text{base}}^{\text{exponent}},}
where significand is an integer, base is an integer greater than or equal to two, and exponent is also an integer.
For example:
1.2345
=
12345
⏟
significand
×
10
⏟
base
−
4
⏞
exponent
.
{\displaystyle 1.2345=\underbrace {12345} _{\text{significand}}\times \underbrace {10} _{\text{base}}\!\!\!\!\!\!^{\overbrace {-4} ^{\text{exponent}}}.}
The term floating point refers to the fact that a number's radix point (decimal point, or, more commonly in computers, binary point) can "float"; that is, it can be placed anywhere relative to the significant digits of the number. This position is indicated as the exponent component, and thus the floating-point representation can be thought of as a kind of scientific notation.
A floating-point system can be used to represent, with a fixed number of digits, numbers of different orders of magnitude: e.g. the distance between galaxies or the diameter of an atomic nucleus can be expressed with the same unit of length. The result of this dynamic range is that the numbers that can be represented are not uniformly spaced; the difference between two consecutive representable numbers grows with the chosen scale.
Over the years, a variety of floating-point representations have been used in computers. In 1985, the IEEE 754 Standard for Floating-Point Arithmetic was established, and since the 1990s, the most commonly encountered representations are those defined by the IEEE.
The speed of floating-point operations, commonly measured in terms of FLOPS, is an important characteristic of a computer system, especially for applications that involve intensive mathematical calculations.
A floating-point unit (FPU, colloquially a math coprocessor) is a part of a computer system specially designed to carry out operations on floating-point numbers.
I have a few sets of A2 handguards for $20 each
Carbon Fiber Free Floating 7.25" light weight keep it simple $60
Ruger Skinny handguards comes with proprietary barrel nut so semi floats the handguards $30
Midlength Magpul Moe Handguards 2 sets $30 each
Oh Hunt Chinese lightweight MLOK...
Title says it all. $60 for a finished rack (as pictured). Unfinished rack with all needed hardware is $40, ready for whatever finish you’d like. Good gift idea or could adorn a wall in a home. For sale, also open to trades!
wondering if anyone would like to trade a 5.56 barrel and handguard for my 10" 300 blk. the barrel has not been assembled to a receiver yet and is non-fired same as hand guard both are from Aero. I already have an AR 300 blk
Looking to buy Duck decoys in excellent shape. I live in Eugene, Oregon and will buy floating duck decoys as well as floating goose decoys. Mallards, teal, widgeon, and pintails. Shoot me as pm or a phone number and you can tell me what you have and how much you would like for them.
I have two AR M-LOC free floating hand guards I won't use. One is a Stag 13 inch, the other is a non-named and it is 15 inches. Both have been mounted and used little. All hardware is included. I'd like $100.00 for the stag and $70.00 for the no name. OBO on both, I hope someone can use them.
This handguard is a "take off" rail from a premium PSA upper I purchased and has had minimal usage / in excellent 9 out of 10 condition (as pictured)
PSA 9" Combat SQR "free floating" mil - std 1913 picatiny rail handguard
* Made from 6061-T6 aluminum (definitely strong.. not some knock off...
I bought this used a while back and it has just been sitting in my garage because I don’t have any rifles to put it on. Here’s the catch. It is missing the screws and I haven’t bothered to go looking for them. So you get a great handguard at an affordable price. Meet in Gresham area and no...
Things in really nice condition and works well. Comes with two cards and new batteries. No mounting hardware/foam/light.
Run the card over an rfid sensor on top and the shelf opens.
$150 or trade for a small handgun safe with some sort of secondary entry method and good reviews. Or whatever...
