1. The problem is to convert a given number to a whole number. 2. Whole numbers are non-negative integers: 0, 1, 2, 3, ... 3. To convert a number to a whole number, we typically round it to the nearest integer. 4. The rounding rule is: if the decimal part is 0.5 or greater, round up; otherwise, round down. 5. For example, if the number is $x = 3.7$, then rounding gives $4$. 6. If the number is $x = 2.3$, then rounding gives $2$. 7. If the number is negative, rounding to a whole number still applies but the result may not be a whole number since whole numbers are non-negative. 8. Therefore, if the original number is negative, converting to a whole number means taking the absolute value and then rounding. 9. Please provide the specific number to convert for an exact answer.
