## Excel HEX2OCT Function

### Description

The Excel HEX2OCT function converts a hexadecimal number to an octal number.

### Syntax and arguments

Formula syntax

HEX2OCT(number, [places])

Arguments

 Number: Required, the hexadecimal number that needed to be converted to an octal number. The number cannot contain more than 10 characters (40 bits). The first bit of the number indicates if the number is positive or negative, and 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 octal number will be padded out using leading zeros, such as HEX2OCT("01",2) returns 01. If it is omitted, HEX2OCT uses the minimum number of characters necessary, such as HEX2OCT(1) returns 1. If the argument number is negative, the places value will be ignored, and returns a 10-character octal number. If argument places is a decimal number, it will be truncated to an integer.

### Return Value

The HEX2OCT function returns to an octal number.

### Error

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

• Argument number is > FFE0000000 or < 1FFFFFFFFF or an invalid value;
• Argument places is provided not enough for the argument number, such as HEX2OCT(“1110”,2) returns #NUM!, because the correctly result is 10420.
• Argument places is < = 0.

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