Frequently Asked Questions
What does round half away from zero mean?
Under this standard rule, a value exactly halfway between two rounding targets moves away from zero, so 123.5 rounds to 124 and negative 123.5 rounds to negative 124.
What is negative 123.5 rounded to the nearest whole number?
Negative 123.5 sits exactly halfway between negative 123 and negative 124, and under the standard rounding rule it rounds away from zero to negative 124.
What is the difference between floor and ceiling rounding?
Floor rounding always moves toward negative infinity, so 4.1 becomes 4 and negative 4.1 becomes negative 5. Ceiling rounding always moves toward positive infinity, so 4.1 becomes 5 and negative 4.1 becomes negative 4.
