HEX2OCT
Converts a hexadecimal number to octal.
This function is only available if the Analysis AddIn is installed.
Syntax:
HEX2OCT(hexadecimalnumber; numdigits)
- returns text representing an octal number, given hexadecimalnumber, which may be text, or a number (taken to be hexadecimal although it is not).
- The octal number returned may have up to ten digits in twos complement representation; positive numbers are 0 to 3777777777 octal and negative numbers 7777777777 to 4000000000 (a range of -2^{29} to 2^{29}-1 decimal).
- hexadecimalnumber must therefore also lie in this range, and is given in twos complement form with up to ten digits.
- numdigits is an optional number specifying the number of digits to return.
Example:
HEX2OCT("1D")
- returns 35 as text.
HEX2OCT(10)
- returns 20 as text. The number 10 is read as hexadecimal.
HEX2OCT("1D"; 3)
- returns 035 as text. HEX2OCT adds a leading zero to make 3 digits.
HEX2OCT("FFFFFFFFFE")
- returns 7777777776 as text (twos complement representation of decimal -2).
