[newbie] What means 1_000_000

[EdUarDo]

Hi all,
trying ri and reading documentation for Benchmark I've seen an example
that says:

Benchmark.measure {"a"*1_000_000}

What's that literall? I've tried to do it with 1000000 instead of 1_000_000 and
it works too.

And what means the expression "a"*1000000? What do that?

Benchmark.measure {"a"*1_000_000}

What's that literall? I've tried to do it with 1000000 instead of
1_000_000 and it works too.

It *is* the same, only more friendly for human readers.

And what means the expression "a"*1000000? What do that?

Why don't you just try it in irb?

irb(main):001:0> "a" * 10
=> "aaaaaaaaaa"

It's that simple
