of over 158 days using Alexander Yee's y-cruncher. Practical approximations Depending on the purpose of a calculation, can be approximated by using fractions for ease of calculation. The most notable such approximations are (relative error of about 4·10−4) and (relative error of about 8·10−8). Non-mathematical "definitions" of Of some notability are legal or historical texts purportedly "defining " to have some rational value, such as the "Indiana Pi Bill" of 1897, which stated "the ratio of the diameter and circumference is as five-fourths to four" (which would imply "") and a passage in the Hebrew Bible that implies that . Indiana bill The so-called "Indiana Pi Bill" from 1897 has often been characterized as an attempt to "legislate the value of Pi". Rather, the bill dealt with a purported solution to the problem of geometrically "squaring the circle". The bill was nearly passed by the Indiana General Assembly in the U.S., and has been claimed to imply a number of different values for , although the closest it comes to explicitly asserting one is the wording "the ratio of the diameter and circumference is as five-fourths to four", which would make , a discrepancy of nearly 2 percent. A mathematics professor who happened to be present the day the bill was brought up for consideration in the Senate, after it had passed in the House, helped to stop the passage of the bill on its second reading, after which the assembly thoroughly ridiculed it before postponing it indefinitely. Imputed biblical value It is sometimes claimed that the Hebrew Bible implies that " equals three", based on a passage in and giving measurements for the round basin located in front of the Temple in Jerusalem as having a diameter of 10 cubits and a circumference of 30 cubits. The issue is discussed in the Talmud and in Rabbinic literature. Among the many explanations and comments are these: Rabbi Nehemiah explained this in his Mishnat ha-Middot (the earliest known Hebrew text on geometry, ca. 150 CE) by saying that the diameter was measured from the outside rim while the circumference was measured along the inner rim. This interpretation implies a brim about 0.225 cubit (or, assuming an 18-inch "cubit", some 4 inches), or one and a third "handbreadths," thick (cf. and ). Maimonides states (ca. 1168 CE) that can only be known approximately, so the value 3 was given as accurate enough
