I don't understand this example. What does it mean
when the second parameter is a negative value?
The help file does not say anything about it.

The help file runtime/doc/eval.txt gives those examples
and the last one looks incorrect:
echo round(4.5)
< 5.0 >
echo round(-4.5)
< -5.0 >
echo round(4.583, 2)
< -5.0
