OCT2HEX function

Converts an octal number to hexadecimal.

Syntax

OCT2HEX(number,places)

Number     is 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     is 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.
