Description mycalb 2014-03-17 03:34:15 UTC
Problem description: 
Isn't it time someone stepped out from the 1985 pack and offered a spreadsheet package at the top of the IEEE 754 standard - quad precision? 
 
Steps to reproduce:
1. ....just type more than 15 digits into a cell
2. ....or multiple any 8 digit number by any 9 digit number
3. ....etc

Current behavior:
the answer always ends in zero
Expected behavior:
Either a warning that the answer is inaccurate, or better still, the correct answer.

              
Operating System: All
Version: 4.2.1.1 release

This is presumably a reference to IEEE 754-2008 (ISO/IEC/IEEE 60559:2011) "binary128" quadruple precision floating point, over and above the original IEEE 754-1985 "binary64" double precision. Summary amended for clarity.

This would appear to be an enhancement request, thus Severity set to enhancement. Status set to NEW, so that Calc developers can comment of the feasibility of this request.

Bug 37923 is possibly also related.
