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.
