<pre>Description:
In MS Excel the formulae DEC2BIN, DEC2OCT, and DEC2HEX have valid inputs as
integers m in the range -2^n <= m < 2^n, where n is given by
DEC2BIN: n=9
DEC2OCT: n=29
DEC2HEX: n=39
LibreOffice Calc gets this right for DEC2BIN and DEC2OCT, but not DEC2HEX.
There, the valid range is erroneously: -2^39 - 1 <= m < 2^39 + 1.
In other words, in Excel we have:
=DEC2HEX(2^39) == #NUM!
=DEC2HEX(-2^39 - 1) == #NUM!
But in LOCalc:
=DEC2HEX(2^39) == "8000000000"
=DEC2HEX(-2^39 - 1) == "7FFFFFFFFF"
This is surprising and does not seem like intended behaviour. I have not yet
investigated whether the other base conversion functions have inconsistent
bounds as well.
Steps to Reproduce:
In a cell do =DEC2HEX(2^39) or DEC2HEX(-2^39 - 1)
Actual Results:
Answers are "8000000000" and "7FFFFFFFFF" respectively.
Expected Results:
Answers should be #NUM! in both cases, in accordance with Excel.
Reproducible: Always
User Profile Reset: No
Additional Info:
OS: Manjaro Linux
LibreOffice Calc version: 6.4.7.2</pre>
