A number expressed without fractions or decimals constitutes a whole number. The set of whole numbers includes zero and all positive integers. Converting a decimal value to this form necessitates identifying the nearest integer. In the specific case of -0.143, the nearest whole number is determined through rounding.
Understanding the relationship between decimals and integers is fundamental in various mathematical and computational applications. This conversion is frequently used to simplify calculations, represent data in a more concise format, or meet specific requirements in algorithms and programming. Historical context reveals that the concept of whole numbers predates decimals, reflecting a foundational element in mathematical development.
