Description Laurent Balland 2023-07-24 19:01:19 UTC
Description:
A number format like "0.00E+?0" should display PI() like "3.14E+ 0", as '?' should be replace by a blank if exponent is less than 10. But Calc treats '?' as a '0' and display "3.14E+00".

Steps to Reproduce:
1. In Calc, Format > Cells > Numbers
2. Set Format code to 0.00E+?0
3. Display a value between 1e-9 and 1e10, like PI(), to have only 1 digit in exponent

Actual Results:
Value displayed is 3.14E+00, which corresponds to Format code 0.00E+00

Expected Results:
Value should be displayed as 3.14E+ 0 with a blank instead of the first '0'


Reproducible: Always


User Profile Reset: No

Additional Info:
Excel correctly treats this format code.
