Actually, I work in analytics well inside the commercial sector. 10 digits of accuracy works most of the time, and when it doesn't there are other alternatives. As with anything there are trade-offs.

I wish more languages would do this and I happily applaud Perl 6 and go for allowing sane operations in the real space without needing separate packages.

But there are high quality packages for all modern languages that allow you to get precision if you need it.

I'm not debating the utility of this feature, but I am saying it's not--by itself--going to make me want to pick up Perl 6 for my next project.
