{"product_id":"9780942208528","title":"Pi to 500k Decimal Places","description":"The power of pi is not immedately evident from a glance at this small Greek letter. Yet the existence of pi has confounded mathematicians and engineers for centuries. What does it mean to have a real number that cannot be stated exactly? What is a number that does not appear to have any recurring pattern? And why does it crop up in unexpected places that have no apparent connection with the circumference of a circle? These questions are not answered in this book, but you do get a glimpse of the phenomenon-real numbers to grapple with. A bit of the history of pi. And a program designed to generate as many digits as you'd like.","brand":"Bandanna Books","offers":[{"title":"Default Title","offer_id":47034615136496,"sku":"9780942208528","price":5.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9780942208528_p0.jpg?v=1763871766","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9780942208528","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
