With computers it is often bit (binary digit) patterns that matter and with octal or hexadecimal numbers it is easy to convert them to binary as each digit is represented by an exact number of binary digits (3 for octal, 4 for hexadecimal) without any waste.Using *nix access permissions as an example, the basic permissions are split into 3 groups (Owner, Group, World), each with 3 possible permissions (Read, Write and eXecute). These are stored as a bit pattern: if set the permission is granted, if not set permission is not granted. A file with rwxr-x--x (rwx for owner, r-x for group and --x for world) is stored in binary as 111101001 which can be represented in octal easily by reading it in groups of 3 bits: 111101001 → 111 101 001 = 0751, or in hexadecimal by splitting it into groups of 4 bits: 111101001 → 1 1110 1001 = 0x1e9; but to convert it to decimal requires: 256 + 128 + 64 + 32 + 8 + 1 = 489.Similarly, going the other way: what permissions are represented by 420?420 to binary:420 ÷ 2 = 210 r 0210 ÷ 2 = 105 r 0105 ÷ 2 = 52 r 152 ÷ 2 = 26 r 026 ÷ 2 = 13 r 013 ÷ 2 = 6 r 16 ÷ 2 = 3 r 03 ÷ 2 = 1 r 11 ÷ 2 = 0 r 1→ 420 = 110100100 in binary = rw-r--r--420 in octal is 0644 and in hexadecimal is 0x1a40644 to binary: 110 100 100 → 110100100 as before [much quicker and easier]0x1a4 to binary: 1 1010 0100 → 110100100 again.

E2 in hex is 1110 0010 in binary
1110 0101 1101 1011 is E5DB
Each hexadecimal digit represent four binary bits. Using the table... 0 = 0000 1 = 0001 2 = 0010 3 = 0011 4 = 0100 5 = 0101 6 = 0110 7 = 0111 8 = 1000 9 = 1001 A = 1010 B = 1011 C = 1100 D = 1101 E = 1110 F = 1110 ... replace each hexadecimal digit with its correspnding binary digits. As an example, 37AB16 is 00110111101010112.
1110
1110-111 in binary = 999
The number 14 in binary is 1110
Hexadecimal means 16. So that 4 binary bits are represented by a hexadecimal number. 0000 = 0 1000 = 8 0001 = 1 1001 = 9 0010 = 2 1010 = A 0011 = 3 1011 = B 0100 = 4 1100 = C 0101 = 5 1101 = D 0110 = 6 1110 = E 0111 = 7 1111 = F
