Description: The ‘FLOOR’ function in DAX (Data Analysis Expressions) is a fundamental tool for handling numerical data in data models. Its main purpose is to round a number downwards, that is, towards zero, to the nearest specified significance multiple. This function is especially useful in situations where precise control over numerical values is required, such as in financial calculations, statistical analysis, or report preparation. By using ‘FLOOR’, users can ensure that results do not exceed certain limits, which is crucial in contexts where precision is vital. The syntax of the function is straightforward: it requires the number to be rounded and the multiple to which it should be rounded. This allows for great flexibility and adaptability in its application, as it can be used with different types of data and in various situations. In summary, ‘FLOOR’ is a powerful function that helps analysts manage and present data more effectively, ensuring that results are consistent and tailored to the specific needs of each analysis.
