Important: just because it is a 64-bit .EXE does not mean that it supports 64 bit integer values (I'm looking at you, Excel). If you don't understand what 64 bit precision is, please don't just Google & suggest something.
I am looking for a gratis spreadsheet which will:
- run on Windows
- support true 64 bit integer values (with no floating point involved)
- support charting of those values
