What constitutes a floating point operation (a FLOP)?

The Aggregate: Frequently Asked Questions about KASY0
Obviously, any operation on a floating-point value, right? Well, yes and no.

What is so ''unsafe'' about floating point?

Infrequently Asked Questions in comp.lang.c
Have you tried EXAMINE STICK? The stick has a sharp point, which punctures the raft, which no longer floats. Don't bring the stick into the raft with you.

What constitutes a point-in-line?

Fencing Online
According to Article 233 section 6 of the FIE Rules of Competition, a point-in-line is a position "with the arm straight and the point threatening the valid target". Properly done, the arm should be extended as far as possible, and form a more or less continuous line with the blade, with the point aimed directly at the high lines of the target. Excessive angulation at the wrist or fingers negates the point-in-line.

Is floating point arithmetic supported?

SystemCrafter - FAQ
No, floating point is not supported by SystemCrafter SC Version 2.0. Floating point hardware implementations are extremely resource intensive and floating point algorithms can normally be more efficiently realised using integer arithmetic.

What are floating-point numbers?

Frequently Asked Questions (FAQ)
A floating-point number is a number that has a fractional part; it is written with a decimal point, e.g.: 2.5, 3.141, -5.99. Floating point numbers are distinguished from integers, which have no fractional part. In Java, there are two types of floating-point numbers, those of type float and those of type double. Numbers of type double have higher precision than those of type float. By default, we will use double for floating-point numbers in CS111.

How to convert floating point decimal to binary?

JavaChina: SCJP Questions & Answers by Roseanne Zhang (8...
In the integer part, you devide by 2. In the decimal part, you multiply by 2 Decimal Binary 2 10 4 100 8 1000 16 10000 0.5 0.1 0.25 0.01 0.125 0.001 0.0625 0.0001 ... You should get my point now.

How can I handle floating-point exceptions gracefully?

System Dependencies
On many systems, you can define a function matherr which will be called when there are certain floating-point errors, such as errors in the math routines in <math.h>. You may also be able to use signal (see question 19.38) to catch SIGFPE. See also questions 14.9 and 20.6b.

How can I store a floating point number into an integer?

COSC 2410: Computer Organization and Programming Lab Web Pag...
FIST stores the value in ST to the specified memory location or register. Temporary-real values in registers are converted to the appropriate integer, BCD, or floating-point format as they are stored. With FSTP, FISTP, and FBSTP, the ST register value is popped off the stack. Memory operands can be 32-, 64-, or 80-bit real numbers for FSTP, or 16-, 32-, or 64-bit integers for FISTP.

Can you change or enter floating point values?

Binary file editor for Windows, FAQ
You can enter a new floating point value in the fields of the Properties dialog. Just type the new value into the "value" field and press Enter (or Esc to abort). You can enter IEEE floating point values using the "IEEE" page or IBM floating point values using the "IBM FP" page. You can also change the byte-order using the "Big-endian" check box and enter 32-bit or 64-bit values depending on the format selected.

Why doesn't my floating-point comparison work?

Newbie Questions / Answers Updated! , C++ FAQ Lite
Why is cos(x) != cos(y) even though x == y? (Or sine or tangent or log or just about any other floating point computation) New!

What constitutes a "Custom Operation"?

Illinois Department of Agriculture - Meat and Poultry
A "Custom Operation" is one in which a person or entity offers slaughter and/or processing services to the public for a fee. The animal to be slaughtered or the meat to be processed belongs to the customer, not the establishment. After the services are rendered, all of the resultant material must be returned to the owner of the animal or altered in an approved manner to prevent its use as food.

Why does a decimal point not indicate floating-point?

comp.lang.forth Frequently Asked Questions (1/6): General/Mi...
In the old days Forth did not have floating-point numbers; instead, fixed-point arithmetic was used, usually on double-cell numbers. So, a decimal point indicated a double number (the position of the decimal point was stored in the variable DPL for potential use by fixed-boint software). In ANS Forth, a decimal point at the end indicates a double-cell number, and an E in the number indicates a floating-point number (when BASE is decimal). All other ways to write numbers are system-dependent.

How do I add a Top or Flop?

Bookswapper FAQ - All About tokens books how to swap books a...
Go to my books, click on "add a top or flop", type in title and author, and give others some idea why you chose this particular book. It doesn't have to be a book listed (by you or someone else) here at bookswapper. Simply clicking on a listed book and adding it to your Tops and Flops is not possible. You have to enter title and author manually. if you have a question not answered here, log on to your account and go back to this page to submit it!

How do you do the operation?

Cardiovascular of Southern Nevada - FAQs
Many of the operations can be found on the Internet, but also prior to operation your surgeon will be glad to discuss the technical portions of the operation. Some patients want to know exactly how each stitch is placed and others do not want to know much about the technical portions of the operation. Please feel free to discuss this with your surgeon.

How do I enable software assisted floating point numbers?

Gentoo Linux Documentation -- Gentoo Linux/Alpha Frequently ...
You can enable software assisted floating point numbers with -mieee. This will enable software assistance to correctly support denormalized numbers and exceptional IEEE values such as not-a-number and plus/minus infinity.

How can I make a floating point comparison function for use with qsort?
