This article describes the formula syntax and usage of the DEC2OCT function (function: A prewritten formula that takes a value or values, performs an operation, and returns a value or values. Use functions to simplify and shorten formulas on a worksheet, especially those that perform lengthy or complex calculations.) in Microsoft Excel.
Converts a decimal number to octal.
The DEC2OCT function syntax has the following arguments (argument: A value that provides information to an action, an event, a method, a property, a function, or a procedure.):
- Number Required. The decimal integer you want to convert. If number is negative, places is ignored and DEC2OCT returns a 10-character (30-bit) octal number in which the most significant bit is the sign bit. The remaining 29 bits are magnitude bits. Negative numbers are represented using two's-complement notation.
- Places Optional. The number of characters to use. If places is omitted, DEC2OCT uses the minimum number of characters necessary. Places is useful for padding the return value with leading 0s (zeros).
- If number < -536,870,912 or if number > 536,870,911, DEC2OCT returns the #NUM! error value.
- If number is nonnumeric, DEC2OCT returns the #VALUE! error value.
- If DEC2OCT requires more than places characters, it returns the #NUM! error value.
- If places is not an integer, it is truncated.
- If places is nonnumeric, DEC2OCT returns the #VALUE! error value.
- If places is negative, DEC2OCT returns the #NUM! error value.
The example may be easier to understand if you copy it to a blank worksheet.
