Pi Day has come full circle again, and to celebrate the irrational number Microsoft is offering a one-day discount of 31.4 percent on Dell's new XPS 13, which now starts at $685.31 rather than yesterday's $999.

It's only the Core i5 non-touch variant that gets the full 31.4 percent discount, although other variants have been discounted by an even $200.

Other models with the 31.4 percent discount include the Dell Inspiron 13, and the Dell Inspiron 15, which now start at $685.31 and $513.81 respectively.

Given Microsoft's current efforts to push Windows 10 onto the world, the hardware discounts are fitting. Last Pi Day, Microsoft offered Pi-based discounts on Xbox music.

Microsoft has also kicked off its spring sale and is offering $100 off the 128GB and 256GB Intel Core i5 Surface Pro 4 models.

The price for the Xbox One and Kinect bundle has also been slashed by $100, now available for $399, along with two free games.

And Microsoft has lopped off $75 from the Band 2, which is available for $174.99.

The items on sale as part of Pi Day are only available today, March 14, while items discounted for Microsoft's Spring sale are available until stocks run out. It's also offering some big discounts on several other PCs and laptops.

Microsoft isn't the only tech organization celebrating Pi. For those looking for something more than satisfying consumer needs, NASA's Jet Propulsion Laboratory is celebrating the day with a new challenge dubbed 'Pi in the Sky 3'.

The challenge encourages students to use Pi the way NASA scientists and engineers do, for example, to measure features on Mars.

In this year's challenge, students are given the radius of Saturn's hazy moon, Titan, and asked to figure out what the percentage of the moon's make-up is atmospheric haze.

Another challenge asks how long it takes for the Mars Reconnaissance Orbiter to orbit the red planet, given its polar diameter and the orbiter's distance at each pole. NASA will publish the correct answers on March 16.
