Oh, dude, the BCD number system is like that old-school friend who still uses a flip phone. The advantage is it's easy for humans to read since each decimal digit is represented by a 4-bit binary number. But the downside is it's not very efficient in terms of storage space compared to other number systems. So, like, it's great for nostalgia but not so much for modern computing efficiency.
It is called qualitative information. Also, sometimes the information can also be ordinal: this may be coded in numeric form but is not really numeric.
Without any function is impossible. So I'll assume you mean any coded function, in which case the predefined function below is your answer.$string = strrev($string);
It is decimal 35.

Binary coded decimal. Each decimal digit is represented by its binary equivalent.
69 in decimal = 1000101 in binary.
not the same

All I know is that when a number is negative, you convert the decimal into binary and if it is negative you put 1111 before the binary digits.
