            Bug ID: 138220
           Summary: calc: calculation: roundup: rounddown: fail in 7.1
                    alpha
           Product: LibreOffice
           Version: 7.1.0.0.alpha0+ Master
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium

Description:
a 'deflowering'? based on 'search' no bugs have been reported for 'roundup' and
'roundown' yet? 

i stumbled over one: 

=ROUNDUP(-999,12999999999994;11) results in -999,130000000010 instead of the
expected -999,130000000000, 

=ROUNDDOWN(-999,12999999999994;11) results in -999,130000000000
instead of the expected -999.12999999999990

same fail - mirrored - for positive values, 

for those not familiar with it: roundup should round 'away from zero',
rounddown 'towards zero', 

plenty other values affected as well, even shorter ones like '888,1299999999'
which need no change for a round to 11 decimals ... 

'round' looks working correctly on a quick first look, 

no repro in 6.1.6.3, hence 'regression', 

imho critical, data corruption ... 

Steps to Reproduce:
