Counting and Timing a shock sensor

Errrr, nevermind. I forgot I had added the period in when I did the test for length to add the leading zero and blank space. Here’s what I hope is the real fix.

String TimeConvert(long time)
{
// takes the time as argument and returns the time for that hit as a XX.xxs string
  if (time != 0) // Make sure there's a value...
  {
    String tmp3 = String(int((time + 5)/10)); // round msecs into csecs
    int k = tmp3.length();  // k will be index to last char in padded string
    int km1 = k-1;          // km1 will be index to next to last char
    int km2 = k-2;          // km2 will be position of period
    tmp3 = tmp3 + '0';  // pad the end of the truncated string with a zero
    //now move chars to make space to add a period
    tmp3.setCharAt(k, tmp3.charAt(km1));   // move next-2-last to last position in string
    tmp3.setCharAt(km1, tmp3.charAt(km2)); // move char to next-2-last position
    // now insert period
    tmp3.setCharAt(km2, '.');
    // add a blank or 2 as needed to get 5 digits with time right justified
    if(tmp3.length() < 4)
    {
      tmp3 = " 0" + tmp3;     // must be a sub 1 sec time add a blank and a leading 0
    }
    else
    {
      if (tmp3.length() < 5)
      {
        tmp3 = ' ' + tmp3;    // must be a sub 10 sec time add a blank to justify
      }
    {
    // tmp3 now holds rounded time in secs XX.xx format
    tmp3 += 's':       // add s for seconds
    return tmp3;
  }
  else
  {
    String tmp3 = "      "; // If the time variable is zero pass 6 blanks back as a string...
    return tmp3;
  }
}

What were you saying about drunk college students writing crap code … :oops:
