Calculations and Data Types

The last chapter introduced the terminology and concepts behind FileMaker's calculations. You learned how to create them using the Specify Calculation dialog box's tools. Functions, as you saw in the previous chapter, play a big role in good calculation construction. In this chapter, you'll learn the details about the most common functions for the various data typestext, number, date, time, timestamp, and containerand when to use them. As in your FileMaker design life, if you want to test a calculation, just create a calculation field and start building it using the techniques you've learned so far. If it doesn't work the way you expect, or if you don't need it after your experiment is done, just delete the field.
