0x2CA
0x2CA is a hexadecimal notation representing the decimal value 714. In computer science and programming, hexadecimal is a base-16 numeral system that uses sixteen distinct symbols, typically 0-9 and A-F. The prefix "0x" is a common convention to indicate that a number is written in hexadecimal. Therefore, 0x2CA signifies the number two, followed by the digit C, followed by the digit A in base 16. To convert this to decimal, we multiply each digit by its corresponding power of 16 and sum the results. The rightmost digit (A) is multiplied by 16^0, the middle digit (C) by 16^1, and the leftmost digit (2) by 16^2. Since A in hexadecimal corresponds to 10 in decimal and C corresponds to 12, the calculation is (2 * 16^2) + (12 * 16^1) + (10 * 16^0) = (2 * 256) + (12 * 16) + (10 * 1) = 512 + 192 + 10 = 714. This value, 714, is the decimal equivalent of the hexadecimal number 0x2CA. Hexadecimal is frequently used in computing for representing memory addresses, color codes, and data in a more human-readable format compared to binary.
