The IEEE 754 standard covers decimal floating point arithmetic, too. Decimal floating point avoids issues like 0.1 + 0.1 + 0.1 not being equal to 0.3 despite usually being displayed as 0.3. Maybe it's reasonable to use that instead?
Some earlier spreadsheets such as Multiplan used it (but not in the IEEE variety) because it was all soft-float for most users anyway.
