Let’s write the closest value to π by using all digits 0 – 9 once each
(1 – 23 + 45 * 67) / 890 = 2993/890 = 3.3629213483146067415730337078651685393258426966292134…
2993/890 – π = 0.2213286947248135031103903245856656551286732972541076…
Better approximations:
1/(234 + 56 – 7) * 890 = 890/283
= 3.1448763250883392226148409893992932862190812720848056…
890/283 – π = 0.0032836714985459841521976061197904020219118727096998…
0 + 1 + 2 + 3/(4*5) – 6/(78*9) = 7351/2340
= 3.1414529914529914529914529914529914529914529914529914…
Repeating decimal: 3.14145299
With 10 digits accuracy:
3 + 4/28 – 1/(790 + 5/6) = 104348/33215
= 3.1415926539214210447087159415926539214210447087159415…
Repeating decimal: 3.1415926539214210447087159
