# Convert hexadecimal to binary and decimal

Form the each group Hex number together in the same order. Binary to Octal Conversion Binary to Octal conversion can be done by divide the bits into groups from right to left side, each containing 3 bits.

If the group is lack of 3 bits then add 0 or 0s to the left hand side to make sure each group containing 3 bits. The below solved example let the users to understand how to convert binary to octal number.

Split the given binary number into groups from right, each containing 3 bits. Add 0 or 0s to the left side if any group is lack of 3 bits. Find the Octal equivalent for each group. Form the each group Octal number together in the same order. Worksheet for Binary to Decimal, Hexa and Octal number conversion. Decimal to Octal Conversion Worksheet. Decimal to Binary, Hexa, Octal Converter. Hexa to Decimal, Binary, Octal Converter.

Octal to Binary, Hexa, Decimal Converter. Number to Word Converter. Any idea how to return ""? Oh, this also omits any leading '0's so it may need padded for this use. If the input is "1a" this gives "", not "" which may or may not be what you want. There are an infinite number of leading zeroes on every number, so I'd hope it omits them.

It's unfortunate that it's a global builtin. It should have been int. It's quite reasonable to need the leading zeros and to not need them. You might want the null byte 0x00 to be eight zero bits for example - this is important for some applications.

Also the OP has a leading zero in his example but I suspect that's just random in this case! Simple 2 3. John La Rooy k 33 Markus 1, 1 10 The new f-strings in Python 3. Convert hex to binary, 42 digits and leading zeros?

We have several direct ways to accomplish this goal, without hacks using slices. First, before we can do any binary manipulation at all, convert to int I presume this is in a string format, not as a literal: Use the builtin function, format Then pass to format: To break that down, here's the grammar form of it: They use the same mini-language formatting rules: And since 42 bits divided by 8 bits per byte equals 6 bytes: Here's a fairly raw way to do it using bit fiddling to generate the binary strings.

The key bit to understand is: John Montgomery 5, 1 24 I know this is old, but what exactly is the point of the "and 1"? It's for the old days of python before the ternary operator.

We only want a one or zero, so that "and 1" is there to ensure that. This script worked best for me to convert a crypto private key in hex to binary for testing purposes. Does anyone know how to split the binary string into 8 bit chunks and print it out? RobotHumans 6 MarianD 3, 5 12 Replace each hex digit with the corresponding 4 binary digits: DmitryK 4, 1 12 Or replace each pair of hex digits with the corresponding 8 binary digits, or replace each triplet of hex digits with the corresponding 12 binary digits
