title: What is the maximum value of a number in Lua?
body: <p>There doesn't seem to be a clear answer to this in the documentation.</p>
  
  <p>I'm interested in incrementing a variable <code>time</code> that counts the seconds since the program started. If the maximum value can count far into the future, like 100 years, then I don't care about letting the variable increment forever. Otherwise I'm going to have to think of a good point to reset <code>time</code> back to 0.</p>
