ldii

ldii refers to the second digit of the last two digits of a year, when those digits are considered individually. For example, in the year 1998, the last two digits are 98. The first digit is 9 and the second digit is 8. Therefore, for the year 1998, ldii would be 8. This is a simple numerical decomposition. It is not a widely recognized or standardized term and is likely to be used in specific contexts, perhaps for data entry, pattern recognition, or very niche mathematical or computational applications where breaking down year digits is necessary. The concept is straightforward and relies on the base-10 numeral system. It can be applied to any year by taking the year number, performing a modulo 100 operation to get the last two digits, and then performing an integer division by 10 on that result. For instance, to find the ldii of 2023: 2023 % 100 = 23. 23 / 10 = 2 (integer division). So, the ldii of 2023 is 2. This method effectively isolates the tens digit of the last two digits of a year.
