The ROUNDUP function
Always rounding up: a number of boxes, pages, started days. 2.1 becomes 3.
Syntax
=ROUNDUP(number, num_digits)
In a French Excel: =ARRONDI.SUP(nombre; no_chiffres).
Arguments
- number: the value.
- num_digits: 0 for whole numbers, 2 for cents, -1 for tens.
An example
=ROUNDUP(A2/12,0)
The number of boxes of 12 for A2 items: a started box counts.
Pitfalls
- Negative numbers round away from zero: -2.1 becomes -3.
- ROUNDDOWN does the opposite: it truncates towards zero.
