#### Elapsed_run_time

Function: elapsed_run_time () Returns an estimate of the number of seconds (including fractions of a second) which Maxima has spent in computations since Maxima was most recently started or restarted. The return value is a floating-point number.

See also `absolute_real_time` and `elapsed_real_time`.

Example:

```          (%i1) elapsed_run_time ();
(%o1)                         0.04
(%i2) expand ((a + b)^500)\$
(%i3) elapsed_run_time ();
(%o3)                         1.26```

```(%o1)                                true
(%i2) ```
