Positional Values for Base-62 Systems X1.1 General X1.1.1 In general, the base or radix is the number of unique digits that a positional numeral system utilizes to represent a string of numbers or values Examples of positional numeral systems include decimal (base-10), octal (base-8), hexadecimal (base-16), etc In the positional numeral systems, it is important to note that there is a difference between the character and the positional value representing that character X1.1.2 This particular specification utilizes the base-62 encoding system which utilizes integer values from “0” to “9” and both the lowercase and uppercase alphabet characters Table X1.1 represents the positional values corresponding to a particular character X1.1.3 Therefore, from Table X1.1, the position of 27 corresponds to the number or value of “r” The position of 61 corresponds to “Z” The position corresponds to the number or value “6” X1.1.4 The remainder of this Appendix shows examples for converting the initial integer string for the manufacturer’s lot code and size into the final base-62 encoding alphanumeric characters X1.1.5 For the remainder of this Appendix, the term “TRUNC” represents truncating or shortening the calculated result by taking only the integer value and dropping the decimal value Positional Value Character 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26
