What the AI looks for in Basic Office Calculators
- Digits
- 10 digits for general office use; 12 digits for accounting or large totals. Overflow on large figures forces you to work around the calculator.
- Display angle
- Choose a tilted or adjustable display for desktop use. A flat display is hard to read without leaning over it.
- Key travel and rollover
- Prefer plastic keys with a positive click over flat membrane keys. Missed or double keystrokes are the main source of errors in fast entry.
- Check and correct
- Needed if you add long columns and must review entries; it is usually found on 12-digit models. It lets you scroll back through entries and fix one without re-keying the whole column.
Brands that matter
- Canon: Its LS and WS desktop lines have solid key feel.
- Casio: Its MS, JF and DM desktop lines range from compact to extra-large.
- Sharp: Practical desktop models from its office line.
What to avoid
- Solar-only units for poorly lit desks.
- 8-digit models for payroll or ledger work.
