To execute a function <code>F</code> once and get the amount of time it took to execute with value <code>v</code>, you can do this:
<lang bqn>F •_timed v</lang>
<code>•_timed</code> is a system value that runs <code>F</code> a set number of times and returns the average runtime of the function. Here, since the left argument <code>𝕨</code> is omitted, it is run once.
The final result is in seconds.
Here are a few example runs:
<lang bqn> {0:1;𝕩×𝕊𝕩-1}•_timed 100
8.437800000000001e¯05
{0:1;𝕩×𝕊𝕩-1}•_timed 1000
0.000299545</lang>
