Converting numbers between octal, decimal, hexadecimal and binary formats
Converting octal numbers to decimal and the opposite. Same for conversion of numbers in hexadecimal and binary formats.1. Decimal to hexadecimal
Converts the given list of decimal numbers to their hexadecimal format. If lower case wanted, use %x instead of %X.
perl -e 'printf("0x%X\n",$_)for@ARGV'
Example:
perl -e 'printf("0x%X\n",$_)for@ARGV' 10 12 1024
0xA
0xC
0x400
2. Hexadecimal to decimal
Converts a given list of hexadecimal numbers to their decimal format. You can use 0x in front of the hexadecimal numbers or not as you want.
perl -e 'printf("%i\n",hex $_)for@ARGV'
Example:
perl -e 'printf("%i\n",hex $_)for@ARGV' 10 12 AF 0xaf
16
18
175
175
3. Decimal to octal
Converts the given list of decimal numbers to their octal format.
perl -e 'printf("%o\n",$_)for@ARGV'
Example:
perl -e 'printf("%o\n",$_)for@ARGV' 5 6 7 8 9 10
5
6
7
10
11
12
4. Octal to decimal
Converts the given list of octal numbers to their decimal format. You can also give hexadecimal formats as long as you put the 0x in front of them.
perl -e 'printf("%i\n",oct $_)for@ARGV'
Example:
perl -e 'printf("%i\n",oct $_)for@ARGV' 10 18 0777 0xaf
8
1
511
175
5. Decimal to binary
Converts the given decimal numbers to their binary format. You can add a 0b in front of the %b in the expression to have the 0bXXX number format.
perl -e 'printf("%b\n",$_)for@ARGV'
Example:
perl -e 'printf("%b\n",$_)for@ARGV' 0 1 2 3 4 5 6 7 8 9 10
0
1
10
11
100
101
110
111
1000
1001
1010
6. Binary to decimal
Converts the given binary numbers to their decimal format. You can use "0b" formated binaries strings if you want.
perl -e 'printf("%i\n",oct("$_"=~/^0b\d/?$_:"0b".$_))for@ARGV'
Example:
perl -e 'printf("%i\n",oct("$_"=~/^0b\d/?$_:"0b".$_))for@ARGV' 10 11 101 1001 0b1011
