0o147
0o147 is a representation of a number. The prefix "0o" indicates that the number is expressed in the octal numeral system, which is base-8. The digits following the prefix, "147", are the octal digits. To convert 0o147 to its decimal (base-10) equivalent, we can use the place-value system. The rightmost digit, 7, is in the 8^0 place. The next digit to the left, 4, is in the 8^1 place. The leftmost digit, 1, is in the 8^2 place. Therefore, the decimal value of 0o147 is calculated as (1 8^2) + (4 8^1) + (7 8^0). This evaluates to (1 64) + (4 8) + (7 1), which is 64 + 32 + 7. The final decimal value is 103. In binary (base-2), 0o147 is represented as 1100111. In hexadecimal (base-16), it is represented as 67. The octal numeral system is sometimes used in computing, particularly in older Unix-like systems, for representing file permissions or character codes.
