What does FF mean in numbers?
Usage notes The abbreviation ff. is used in citation to refer to a section for which no final page number can usefully be given. If there is only a single section following, f. may be used instead. More properly, it is still used, as originally, to refer to the next page or pages in a citation.

How many carrom pucks can a base 3 hold?
This very powerful visualisation techniques will mean that for a base 3 system you essentially have a tumbler length that can hold 2 carrom pucks only. Same idea for base 10 or base 16, you have tumbler lengths that hold that many carrom pucks, which is base number-1excluding the zero symbol, which is a placeholder.
How to think of hex notation?
Motivation:The simplest way to think of hex notation first is the number of increased symbols to represent more quantity or number of items. Babylonians used a base 60system so you might imagine it’s a lot easier for us. The base of a number representation system really is a count of the total number of items that can be counted using a symbol from the symbol set. Once you get this part, you will suddenly see things very clearly and deal with ‘any’ base number like base 3 or base 7 or base 93 without any conceptual problems.
Why is hex used in math?
I understand that hex is used because it allows for a higher numerical value in a single character space. And it counts 0-9 like normal, and then, A=10, B=11, C=12, D=13, E=14, F=15, and then starts over at 10. So if F=15, then wouldn’t FF (15 x 15) equal 225? But if it’s the case that hex represents 16 characters, and F represents 16, then FF would equal 256. There’s clearlysomething I’m not getting, can anyone help me out?
What is the advantage of hex?
You make it sound like relic of the old age. To me, the advantage of hex is that is goes so well with four. So you can play from a rhythmical offset (slice/Sxx command), all with easily typed numbers like 10,20,30,40 (instead of 16,32,48,64)…hex is easier and faster for these time based things….
How to convert 0xAB to decimal?
To convert a number 0xAB from hex to decimal, just do (16)(A) + B.
Is 0x10 hex better than 0x20?
The benefit is dance music is using 16 steps or beat subdivisions etc so 0x10 denotes 16 steps and 0x20 will be 32 steps and so on, which is why hex is so better for creative tasks when using computers.
What is the base 60 system?
The base of a number representation system really is a count of the total number of items that can be counted using a symbol from the symbol set.
How many bits are in a hex digit?
I'm a bit confused by how, according to the article, 1 hex digit represents 8 bits and 2 hex digits represents 16 bits.
What is extra FF?
The 'extra' FF is an alpha value (degree of transparency). If you only have three hexadecimal pairs, the alpha value is assumed to be ff (no transparency). However, if you compare #335A7F39 and #FF5A7F39, you should see a difference.
What is the meaning of "back up"?
Making statements based on opinion; back them up with references or personal experience.
What does FF mean in color?
That may be the alpha component of the color, which represents the opacity (00 -> transparent, FF -> opaque).
Can RGB be converted to color?
Some RGB values seem not to be convertable into a Color Object
How many digits are in an octal base 8?
The octal (base 8) system can also be converted with relative ease, although not quite as trivially as with bases 2 and 4. Each octal digit corresponds to three binary digits, rather than four. Therefore, we can convert between octal and hexadecimal via an intermediate conversion to binary followed by regrouping the binary digits in groups of either three or four.
What is the prefix for hexadecimal?
Unix (and related) shells, AT&T assembly language and likewise the C programming language (and its syntactic descendants such as C++, C#, Go, D, Java, JavaScript, Python and Windows PowerShell) use the prefix 0x for numeric constants represented in hex: 0x5A3. Character and string constants may express character codes in hexadecimal with the prefix x followed by two hex digits: 'x1B' represents the Esc control character; "x1B [0mx1B [25;1H" is a string containing 11 characters with two embedded Esc characters. To output an integer as hexadecimal with the printf function family, the format conversion code %X or %x is used.
What is 159 16?
A numerical subscript (itself written in decimal) can give the base explicitly: 159 10 is decimal 159; 159 16 is hexadecimal 159, which is equal to 345 10. Some authors prefer a text subscript, such as 159 decimal and 159 hex, or 159 d and 159 h .
How many hexadecimal digits are in a color reference?
Color references in HTML, CSS and X Window can be expressed with six hexadecimal digits (two each for the red, green and blue components, in that order) prefixed with #: white, for example, is represented as #FFFFFF. CSS also allows 3-hexdigit abbreviations with one hexdigit per component: #FA3 abbreviates #FFAA33 (a golden orange: ).
Why are hexadecimal numbers used?
Hexadecimal numerals are widely used by computer system designers and programmers because they provide a human-friendly representation of binary-coded values. Each hexadecimal digit represents four bits (binary digits), also known as a nibble (or nybble). For example, an 8-bit byte can have values ranging from 00000000 to 11111111 in binary form, which can be conveniently represented as 00 to FF in hexadecimal.
What is a subscript in math?
In mathematics, a subscript is typically used to specify the base. For example, the decimal value 59,014 would be expressed in hexadecimal as E686 16. In programming, a number of notations are used to denote hexadecimal numbers, usually involving a prefix. The prefix 0x is used in C which would denote this value as 0xE686 .
What are the numbers above ten?
There are no traditional numerals to represent the quantities from ten to fifteen – letters are used as a substitute – and most European languages lack non-decimal names for the numerals above ten. Even though English has names for several non-decimal powers ( pair for the first binary power, score for the first vigesimal power, dozen, gross and great gross for the first three duodecimal powers), no English name describes the hexadecimal powers (decimal 16, 256, 4096, 65536, ... ). Some people read hexadecimal numbers digit by digit, like a phone number, or using the NATO phonetic alphabet, the Joint Army/Navy Phonetic Alphabet, or a similar ad-hoc system. In the wake of the adoption of he xadecimal among IBM System/360 programmers, Magnuson (1968) suggested a pronunciation guide that gave short names to the letters of hexadecimal – for instance, "A" was pronounced "ann", B "bet", C "chris", etc. Another naming system was elaborated by Babb (2015), off a TV series as a joke. Yet another naming-system has was published online by Rogers (2007) that tries to make the verbal representation distinguishable in any case, even when the actual number does not contain numbers A–F. Examples are listed in the tables below.
