0x128ff

0x128ff is a hexadecimal number, which is a base-16 numeral system used in computing and digital electronics. In this system, the digits range from 0 to 9 and the letters A to F, where A represents 10, B represents 11, and so on up to F, which represents 15 in decimal. The prefix "0x" is commonly used in programming and digital contexts to denote a hexadecimal number.

The hexadecimal number 0x128ff can be converted to decimal by evaluating each digit's contribution to the total value. Starting from the rightmost digit, each digit is multiplied by 16 raised to the power of its position index, starting from 0. For 0x128ff, this would be:

(1 * 16^0) + (8 * 16^1) + (2 * 16^2) + (1 * 16^3) + (f * 16^4)

Where "f" represents 15 in decimal. Calculating this gives:

(1 * 1) + (8 * 16) + (2 * 256) + (1 * 4096) + (15 * 65536)

This equals 1 + 128 + 512 + 4096 + 983040, which sums to 987777 in decimal.

Hexadecimal is often used in computing because it provides a more human-friendly representation of binary-coded values. It is particularly useful in fields such as programming, digital electronics, and data storage, where binary data is commonly represented in hexadecimal format.
