What does round to the nearest dollar mean?
Rounding to the nearest dollar means approximating a money amount to its whole value. For example:
| Original number | Approximation | |
|---|---|---|
| -$123.7 | ≈ | -$124 |
| -$123.5 | ≈ | -$124 |
| -$123.3 | ≈ | -$123 |
| $456.7 | ≈ | $457 |
| $456.5 | ≈ | $457 |
| $456.3 | ≈ | $456 |
In other words, we don't deal with cents and only stay with whole dollars. It's a simple process, but we must consider the value of the cents (the numbers after the decimal point) to correctly round to the nearest whole dollar. Let's look at how to do it.
How to round to the nearest dollar
Rounding to the nearest dollar is a straightforward process. We must simply look at the digit in the tenth place (the first decimal) and apply the following rules:
- If the first decimal digit is 5 or more, we increase the whole part by one unit.
- For example, $34.57 rounded to the nearest whole dollar is $35.
- If the first decimal digit is less than 5, we leave the whole part as it is.
- For example, $45.19 rounded to the nearest dollar is $45.
The rule previously mentioned is the most common rounding method, called half up rounding. Even so, there are other (less common) rounding modes, which you can enable by ticking the Show advanced rounding modes option at the bottom of the calculator.
