vs

Binary

Binary, the base-2 numeral system, represents numbers using two symbols: 0 and 1

Hex

Hexadecimal (also base 16, or hex) is the base-16 positional numeral system, using the 16 symbols 0–9 and A‒F.

Example

"Just have in mind that the best result is with negative hex and binary integer interpretations simple numbers not so much also with hex you can set up the byte size"

from question

Two's Complement Binary in Python?

"Hex is easier for most people to convert to and from binary in their heads since binary numbers are usually expressed in blocks of eight because that s the size of a byte and eight is exactly two hex digits but hex notation would have been clunky and misleading in dennis time implying the ability to address 16 bits"

from question

Where did the octal/hex notations come from?

Characters conversion input

Example

"If the hex input is more than 5 hex characters you will overwrite the memory allocated for binary_line"

from question

Converting hex to binary and then to decimal

"The conversion from hex to binary is even simpler since you can simply expand each hex digit into the corresponding binary for example 0xa4 - 1010 0100"

from question

Understanding hexadecimals and bytes in C#

"This is still accepted by calls like inet_addr and has several advantages all fields are fixed width there are only 8 characters to update and the binary to hex conversion is usually faster than binary to decimal"

from question

from question

Pymodbus in RaspberryPi 3

"If you consider look at the coa8010b c0 in hex is equal to 192 in decimal a8 168 01 1 and 0b 11;in short this is a binary representation not a string representation of 192.168.1.11"

from question

Null result on Converting NSData to NSString

"Hex is a text serialization format for binary integers;the value in is a 32-bit binary number not hex or decimal"

from question

How to get the decimal number from ASCII code in MIPS?

"Decode 63697a61f161 hex produces the bytea value x63697a61f161 if bytea_encoding is hex or ciza 361a if bytea_encoding is escape;either way it s a representation of a binary string not text"

from question

Postgres - decode special characters

Form decimal too

Example

"Call integer.parseint str 16 in a try-catch if you get a numberformatexception it wasn t a valid hex encoded int;computers perform math with binary not decimal and not hex"

from question

(Java) How to define what letters/numbers/signs are allowed to be input by user?

"First of all 0x00001111 is in hex which is a larger number than 255 - and byte overflows;look here how to represent binary numbers or just use"

from question

"00000001 is really a number and you can writer it on any other form but coincidently for decimal is 1 for hex is 1 too;binary is not olny used as a number system to represent a number but also can represent some objects and used as char"

from question

What is the difference between Assembly and binary?

Example

"It seems the from a readability and usability standpoint the hex representation is a better way of defining binary numbers"

from question

Why do most languages not allow binary numbers?

"Converting between decimal and hex is more involving and at least to me it s been easier if i have to do it in my head to first convert the decimal into binary representation and then the binary number into hex"

from question

Understanding hexadecimals and bytes in C#

Single octal bits

Example

"It is usually better than octal base 8 because each hex digit is 4 bits and binary data is usually arranged in clumps of powers of 2 due to how our computer bit-addressing works"

from question

When we need to convert binary to hexadecimal in real life

"As others have pointed out hex is much more convenient than binary anyway - you just need to remember how each of the hex digit 0-f looks in binary and replace groups of 4 bits with a single hex digit"

from question

Bitwise operations: C vs. Python

"Each single hex character describes four binary digits exactly while an octal character describes 3 binary digits;hex is used much more often than octal"

from question

HELP! I don't know binary, hexadecimal, octal, and bit-wise

Editors files editing

Example

"I ve been using images to store data since editing binary data through paint.net is much friendlier than most hex editors"

from question

What is a the quickest way to bitwise convert two ints to a long in java?

"Do not open hex files in a hex editor because hex editors are designed for editing binary files not text files;a hex file is a text file that you can open in notepad emacs or any standard plain text editor"

from question

AVR: Help me understand assembly to HEX conversion

Others

Example

Base64 is usually used in instances to represent arbitrary binary data in a text format base64 has a 33.3 overhead but that s better than say hex notation which has a 50 overhead

from question

Why use Base64?

Hex encoding is far more readable than binary that s why sublime uses it

from question

- i usually find debugging memory in hex x command is easier than binary so i will not use my solution

from question

Formatting the binary representation of data in gdb

Hex is short more readable and you have less of a chance of leaving a mistake in your code;if you want to be really explicit i d still recommend using the binary literal over the parseint method as it is safer

from question

Java: Thinking in Java 4th edition. Why would one use a hexadecimal here?

But when anyone human looks at machine code anyone human look at machine code in hex using a hex editor which is much easier than reading binary

from question

What does binary in script look like?

If the user can specify several registers in one command invocation then binary is more reasonable though not necessarily wholly reasonable but do consider the merits of hex over binary one hex digit controls the value of four bits

from question

Can I read command line argument as binary?

The reason hex is seen quite a bit in code is simply that it allows the common 8-bit width of bytes to be represented with exactly and just 2 hex digits which is reasonably concise and not too hard for humans to get used to;it s easy enough to mentally convert back to binary while not losing track of which digits you re looking at the way you can with a 32-bit or 64-bit value in binary

from question

Why does C++ break down into nibbles?

The hex file has a checksum on each line;the binary may not have any checks

from question

Advantage for hex formats like SREC or Intel HEX

Unfortunately using hex consumes way more space and takes significantly longer i m dealing with 500gb of data and around 1 2 million records so i would really like to get the straight binary method to work

from question

MySQL blob to file with bash. Why did this corrupt my data?

Since blob stores binary data and not all bytes are displayable the hex code makes more sense to display the data as hex encoded to human readers

from question

How to use HeidiSQL BLOB(hex code) in jsp

The bit shift operators and move each binary digit one place over depending on the direction of the arrows and so on;the hex is just a nicer format to visualize the bits without having to write out every single bit

from question

What is the "0xXXXX" syntax when learning bit manipulation? (where X is a capital alphanumeric character)

Hex is just less verbose and can express anything a binary number can

from question

Why do most languages not allow binary numbers?

Format_int in binary case it loops 4 times then 4 times more than hex and dec cases

from question

Slight Delay After Returning from Interrupt

Those hex values seem a bit odd they re powers of two in decimal but in any case 0x128 the 0x is a standard prefix for hex numbers is the larger of the numbers in magnitude and its binary representation is 100101000

from question

A hex string is significantly longer than the corresponding binary string

from question

Why use bin2hex when inserting binary data from PHP into MySQL?

One important reason is because hex is alot shorter and easier to read than binary is for humans

from question

Importance of Hexadecimal numbers in Computer Science

It does produce hexadecimal rather than binary but it s very likely that hex is what you really want

from question

How to convert a binary byte into a printable numeric value?

If the right side the binary side is greater than or equal to the hex side then you print true if not then you print false

from question

My program works on my computer, but not on CodeEval

Decoding a string of hex characters into a binary slice isn t currently part of the crystal standard library so i wrote a decoding function myself;this function takes a string containing hexadecimal characters then decodes it into a slice uint8 or returns nil if the hex is invalid
