OCT2HEX function

This article describes the formula syntax and usage of the OCT2HEX 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.

Description

Converts an octal number to hexadecimal.

Syntax

OCT2HEX(number, [places])

The OCT2HEX 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 octal number you want to convert. Number may not contain more than 10 octal characters (30 bits). The most significant bit of number 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, OCT2HEX uses the minimum number of characters necessary. Places is useful for padding the return value with leading 0s (zeros).

Remarks

  • If number is negative, OCT2HEX ignores places and returns a 10-character hexadecimal number.
  • If number is not a valid octal number, OCT2HEX returns the #NUM! error value.
  • If OCT2HEX requires more than places characters, it returns the #NUM! error value.
  • If places is not an integer, it is truncated.
  • If places is nonnumeric, OCT2HEX returns the #VALUE! error value.
  • If places is negative, OCT2HEX returns the #NUM! error value.
