Which function allows you to convert values between Money and Quantity types?

The function that allows you to convert values between Money and Quantity types is the CURRENCY functions. These functions are specifically designed to facilitate the conversion of numerical values that reflect financial data (Money) into a format that can be treated as quantities for calculations and analysis, and vice versa.

In practical terms, using CURRENCY functions within a system that manages financial transactions or inventory can help ensure that numerical data is accurately represented and calculated according to the context—whether working with monetary amounts or physical quantities. This versatility is crucial for organizations that need to handle and analyze various types of data seamlessly.

In contrast, the other options serve different purposes. ISNULL is used to check for null values in data, MONEYVALUE is typically used to extract the monetary value from a data structure, and RAWVALUE retrieves the underlying data without conversions. None of these options focus on the specific conversion capabilities of Money to Quantity.
