You can format the number displayed by the computer as the
answer. For instance, if the answer is one-third, the computer will display
that it computed ".333333333" as the answer. If you'd like to shorten
that, you can use the Format field. Format strings like "2E"
(without the quotes) will display three significant digits in scientific
notation. Format strings like "2f" will display two digits after the
decimal point. Format strings like "2s" will round a number to
2 significant digits. For a summary of numerical format statements, see the
num tag item in the Output Tags section ().
