title: Convert integer to string in lua?
body: <p>I've seen lot's of answers to convert strings to integers, but how can I convert integers to strings? When I try <code>microseconds.toString()</code> I get the following error: <code>attempt to index upvalue 'microseconds' (a number value)</code></p>
  
  <p>Please note that this is on a ti-nspire running os 4.5.0.1180</p>
