Bug ID: 167892
Summary: Calc hangs when very low number is formatted as a
fraction
Product: LibreOffice
Version: 25.2.5.2 release
Hardware: All
OS: Windows (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Calc
Assignee: [email protected]
Reporter: [email protected]
Description:
I tried to format the content of the cell A1, 1E-21, as a fraction, then Calc
hangs and become completely unresponsive (I waited for more than 2 minutes).
Steps to Reproduce:
1. Enter in A1: 1E-21 and press Enter. A1 shows 1.00E-21
2. Select the cell A1 and use the menu Format > Cells...
3. Select Fraction in the category column
Actual Results:
Calc hangs immediately after the click on Fraction
Expected Results:
Calc should display the possible formats
Reproducible: Always
User Profile Reset: No
Additional Info:
After trial and error, I noticed that numbers greater than 1.09E-19 can be
formatted as fractions, while numbers smaller than 1.08E-19 triggers the
hang-up.
As 2 ^ 63 is 1.0842E-19, I suspect an overflow in the program.
