Description: The ‘FLOOR.MATH’ function is a DAX (Data Analysis Expressions) tool that allows rounding a number down, towards zero, to the nearest multiple of a specified significance. This function is particularly useful in data analysis, where it is often necessary to adjust figures to more manageable or significant values. By using ‘FLOOR.MATH’, analysts can control the precision of their calculations and presentations, ensuring that results are consistent with industry expectations or standards. The function takes as parameters the number to be rounded and the significance, allowing for considerable flexibility in its application. For example, if one wishes to round a number to the nearest ten, a significance of 10 can be specified. This downward rounding capability is especially valuable in financial contexts, where overestimations are to be avoided and conservative figures are preferred. In summary, ‘FLOOR.MATH’ is an essential function in DAX that facilitates precise manipulation of numerical data, contributing to clarity and accuracy in reports and analyses.
