0o1202

0o1202 is a number represented in octal, also known as base-8. In the octal system, each digit's place value is a power of 8. The number 0o1202 can be interpreted by expanding its digits according to their place values. Starting from the rightmost digit, the '2' is in the $8^0$ (or ones) place, the '0' is in the $8^1$ (or eights) place, the '2' is in the $8^2$ (or sixty-fours) place, and the '1' is in the $8^3$ (or five hundred and twelves) place.

To convert 0o1202 from octal to its decimal (base-10) equivalent, we perform the following calculation: $(1 * 8^3) + (2 * 8^2) + (0 * 8^1) + (2 * 8^0)$. This simplifies to $(1 * 512) + (2 * 64) + (0 * 8) + (2 * 1)$. Calculating these values gives us $512 + 128 + 0 + 2$. Summing these results in a decimal value of 642. Therefore, 0o1202 in octal is equivalent to 642 in decimal. Octal notation is sometimes used in computing, particularly in older systems or for representing file permissions in Unix-like operating systems.
