I had written a well thought out reply to this, but then by browser crashed, so I'll just provide some points on why this script fails:

  • First of all, it's syntactically invalid (this, I assume, is just a type): you provide a " before ($a%100), I assume that isn't meant to be there. Also, you need to place parentheses around your print call so all of the items you want to send go to print.
  • Second, It doesn't account for the fact that the computer cannot store the floating point numbers accurately.
  • Third, it produces output like this: (when the typos are corrected) 
    1.23.23
4.345.34
5.523.52

    You see, you print ($a/100), but if that is a decimal, then it will print (decimal and all!), and then the added decimal will print, not what you want.
  • Last, it doesn't round. The middle number should read 4.35 (after being rounded), but your code (ignoring the extra decimal and just reading from the last), makes it 4.34.
