Example Calculations
First decimal (5) ≥ 5, round up
First decimal (1) < 5, round down
First decimal (5) = 5, round up (half-up)
First decimal (4) < 5, round down
First decimal (9) ≥ 5, round up to next thousand
Negative number: round toward negative infinity
Standard Rounding Rules
Rule 1: First decimal < 5
Keep the whole dollar amount as is
Example: $45.19 → $45
Rule 2: First decimal ≥ 5
Round up to the next whole dollar
Example: $34.57 → $35
Special Case: Exactly $0.50
Standard rule rounds up (half-up method)
Example: $123.50 → $124
Quick Tips
Rounding to the nearest dollar removes all cents
Look at the first decimal place (tenths) to determine direction
Half-up is the most common rounding method
Negative numbers follow the same rounding rules

Common Examples
Advanced Rounding Methods
Half-Even (Banker's)
When exactly halfway (0.50), round to the nearest even number. This reduces bias over many calculations.
$2.50 → $2 (even), $3.50 → $4 (even)
Toward/Away from Zero
Alternative methods that consider the sign of the number and round consistently toward or away from zero.
Toward zero: $2.7 → $2, $-2.7 → $-2
Away from zero: $2.3 → $3, $-2.3 → $-3
