Limiting the digits calculated after 0. ?

Questions
1

Been working on a little calculator project, but the numbers it outputs look kinda messy because Codea calculates so many digits. For example: 1.28547467473725683 As opposed to: 1.28

Is there any way to fix this??

@DJMoffinz Use the string.format() function. There are a lot of options to it, so do a google search or search the forum for examples. To limit the above large number to the smaller one, it would be something like

function setup()  
    print(string.format("%.2f",1.28547467473725683))     
end

which would print 1.29 rounded up.
