Common Errors & Fixes

  • Number rounded in the wrong direction

    Causes:
    • Using ROUNDUP when ROUND or ROUNDDOWN was intended.
    • Negative numbers may give unexpected results if you expect "up" to mean "less negative".
    Fixes:
    • Use ROUND for standard rounding, ROUNDDOWN for truncation.
    • For negative numbers, test with a small sample first.

Frequently Asked Questions

When should I use ROUNDUP instead of ROUND?

Use ROUNDUP when you need to ensure a value never falls below a threshold, such as calculating required materials, shipping charges, or pricing markups.

Does ROUNDUP ever round down?

No. ROUNDUP always rounds away from zero. Even 1.001 rounded to 0 decimals becomes 2. Use ROUNDDOWN for forced rounding toward zero.

How does ROUNDUP handle negative numbers?

ROUNDUP rounds away from zero, so -1.5 becomes -2 (more negative). This is consistent with "always round up" behavior.
