Commas vs. Periods in Different Countries

A quick note before we get started with Tableau.

Depending on your location, decimals and commas may be treated differently (mostly in European countries) than what you will see in this course.

For this course, we will be using a convention where commas separate large values - like 1,000.00 or 1,000,000.00. On the other hand, the period will be used as the decimal separator, as you can see from these previous numbers.

You may want to assure that you are following along with these same conventions, or at least be aware of the differences you may see should you be using a different convention for commas and decimals.
