[Tutor] sales tax

[Michael Langford]

This function can easily found using the google programming rule:

I want a function that does 'action'

Type: <Name of programming language> <action> into google

Look in top 5 results. If that doesn't work, try synonyms for 'action'

     --Michael

PS: The function you're looking for is called round. Its first param is the
number to round, the seconds is how many digits past the radix point to
keep.
