Microsoft truncates

I just got this email from Micrusoft:

In celebration of Pi Day (3.14.15), you can buy a 12-month Xbox Music Subscription for only $31.41 (retail value $99.90). No promo code is required but it’s only available today, while supplies last. Shop now.

I think this was created by the Microsoft marketeers. I think the engineers would have rounded to $31.42.
