            Bug ID: 136794
           Summary: calc: ui: round: calc 'round' is erroneously limited
                    to 20 decimal digits,
           Product: LibreOffice
           Version: 3.5.1 release
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Calc

Description:
i wanted to round small numbers, for example 6.23455E-27 which has 32 decimal
places to 6.235E-27 which has 30 decimal places, and got error messages, 

according to the discussion in: 
https://ask.libreoffice.org/en/question/266009/issue-with-rounding-small-values-round-to-more-than-20-decimals/
- and @Lupp's answer there - it is a bug,  

'=round(6,22735e-27;30)' results in 'Err:502'
'roundsig' as proposed by @erAck can be of help for my originating problem (as
i indeed want to cut off all fp-rounding artefacts, also in the
'pre-decimal-range'), but doesn't help for users who want a value with more
than 20 but limited! decimals, 
importance 'normal' as the workaround with a user defined round macro-function
isn't 'easy' for most users

Steps to Reproduce:
1. key in '=round(6,22735e-27;30)' into a cell, without the quotes, 
2. press enter, 
3. results in 'Err:502', 

Actual Results:
'Err:502'

Expected Results:
6,227e-27


Reproducible: Always


User Profile Reset: No
