Once we have this, I assume we should be able to also get vectorized implementations for columns at basically no additional cost.

I'll implement that in this PR.

Actually I'll make a separate task for this.

roundLong may throw a IllegalArgumentException, but I don't see it being caught and converted to Enso error.

I reverted to the Enso integer round, since it was faster. So this is no longer used.

Looks good - will leave between you and Radek to include a vectorized column approach and as discussed worth looking at being a builtin.

@GregoryTravis what is blocking this PR to be merged?

It needs more varied benchmarks to be run to determine whether to use the Java or Enso implementations.

What's the goal of this change? I've heard something about builtin during the standups. This is not a builtin, right?

The "less builtins the better", but still, I am a bit surprised.

@JaroslavTulach yes, this is not a builtin. I will be benchmarking it as a builtin to see if there is any speed difference, but I wanted to get this in because there's a definite improvement for the decimal case.
