Difference between BCD code and hexadecimal code

For example, for a number: 0000 0010 0011 1111
The hexadecimal format is 23f.
If the code is converted to BCD, because BCD does not have ~ F, then each digit is multiplied by its bit right:
1x1 (0 power of 2) +
1x2 (1 power of 2) +
1x4 (2 to the power) +
1x8 (3 power of 2) +
1x16 (4 power of 2) +
1x32 (5 power of 2) +
0x64 (6 power of 2) +
0x128 (7 power of 2) +
0x256 (Power 8 of 2) +
1x512 (9 power of 2) +
0x1024 (10 power of 2) +
0x2048 (2 to the power of 11) +
0x4096 (12 power of 2) +
0x8192 (13 power of 2) +
0x16384 (14 power of 2) +
0x32768 (the 15th power of 2) = 575
Therefore, the converted BCD code is 0000 0101 0111 0101 (0575)
