This Mathematica program will generate the first nn terms of the sequence:
nn=50; Numerator[With[{pidgs=N[Pi,nn]},Table[IntegerPart[pidgs 10^(n-1)]/10^n,{n,nn}]]]
Best,
Harvey

Subject: [seqfan] Converting from a decimal to the simplest fraction
Hello SeqFans,
Playing around with Georges Brougnard's
"Fractissimo" iPhone App I came to this
for the constant Pi:
3 --> 3/1 --> 3
3.1 --> 31/10 --> 31
3.14 --> 157/50 --> 157
3.141 --> 3141/1000 --> 3141
3.1415 --> 6283/2000 --> 6283
3.14159 --> 314159/100000 --> 314159
3.141592 --> 392699/125000 --> 392699
...
Would it be of interest for the OEIS
to enter the last (numerators) column
as a sequence?
If yes, what about e, phi, Champernowne,
etc.
Best,
É.
