0o1470

0o1470 is a numeric literal written in octal notation, using the 0o prefix to indicate base-8. In languages that adopt this convention, such as Python 3 and modern JavaScript (ES6 and later), the digits that follow must be in the range 0 through 7.

As an octal number, 0o1470 represents a decimal value of 824. This is calculated as 1 × 8^3 + 4 × 8^2 + 7 × 8^1 + 0 × 8^0 = 512 + 256 + 56 + 0 = 824. In hexadecimal, the same value is 0x338.

Usage and context: In Python 3, 0o1470 would be interpreted as an octal literal. In Python 2, octal values were written with a leading zero without the o, such as 01470, which could lead to confusion. JavaScript introduced the 0o prefix for octal literals with ES6, allowing code to express octal values clearly. Some languages historically used leading zeros to signify octal, which can cause bugs when such literals are mistaken for decimal numbers. Understanding the base is important when performing arithmetic, bitwise operations, or when converting between bases for display or storage.
