Syntax and arguments

Formula syntax

OCT2HEX(number, [places])

Arguments

  • Number: Required, the octal number that needs to be converted to a binary number. The number may not contain more than 10 characters (30-bits). The most significant bits of the number indicates if the number is positive or negative, the remaining bits indicate the magnitude of the number. Negative numbers are represented using two’s-complement notation.
  • Places: Optional, the number that specifies the number of characters of the result. If it is greater than the minimum, the result hexadecimal number will be padded out with leading zeros (0s), such as OCT2HEX(2,2) returns 02. If it is omitted, OCT2HEX used the minimum number of characters necessary, such as OCT2HEX(2) returns 2. If the argument number is negative, the place value will be ignored, and returns a 10-character binary number. If argument places is a decimal number, the place will be truncated to an integer.

Return Value

The OCT2BIN function returns a hexadecimal number.

Error

1. Return #NUM! error if one of the below states occurs:

  • Argument number is > 777 or < 7777777000 or an invalid octal value;
  • Argument places is provided not enough for the argument number, such as OCT2HEX(“21”,1) returns #NUM!, because the correct result is 11;

2. Return #VALUE! error if argument places is a non-numeric value.
