Pi (Ï) Ziffern-Explorer.
Holen Sie sich die ersten N Ziffern von Pi, schlagen Sie die Ziffer an einer beliebigen Position nach, suchen Sie in Pi nach einer Zahlenfolge und laden Sie die Ziffern als Textdatei herunter.

So geht's
Die Positionen zĂ€hlen die Ziffern NACH dem Dezimalpunkt: bei 3,14159⊠ist Position 1 die 1, Position 2 die 4 und Position 3 die 1. Die fĂŒhrende 3 ist der Ganzzahlteil und hat keine Position.
Diese Seite enthÀlt die ersten 10.000 Dezimalstellen von Pi. Sie werden exakt mit Ganzzahlarithmetik beliebiger Genauigkeit berechnet, sodass jede angezeigte Ziffer korrekt ist.
Pi ist irrational: seine Ziffern enden nie und bilden nie ein sich wiederholendes Muster, daher sind 22/7 und 3,14 NĂ€herungswerte, keine exakten Werte.
FAQ
What are the first 10 digits of Pi?
Pi to 10 decimal places is 3.1415926535. The full value is 3.14159265358979323846⊠â Pi is irrational, so the digits continue forever without ever repeating. This page shows up to 10,000 exact decimal digits.
Does position 1 mean the 3 or the 1?
Position 1 is the first digit AFTER the decimal point, so position 1 = 1, position 2 = 4, position 3 = 1, position 4 = 5. The leading 3 is the whole-number part and has no position. This is the convention used by every major Pi digit table, and it is the one this tool uses.
Can I find my birthday or phone number in Pi?
Often, yes â use the search mode. A 4-digit sequence like 0704 almost always appears within the first 10,000 digits, and 6-digit sequences usually do too. Longer strings may need millions of digits. If a sequence is not found here, it simply does not occur in the first 10,000 digits; it may still appear later.
How accurate are these digits?
Every digit is exact. They were computed with arbitrary-precision integer arithmetic using Machin's formula and verified against an independent higher-precision run, so there is no floating-point rounding anywhere in the dataset.
Why is Pi not just 22/7?
22/7 equals 3.142857âŠ, which matches Pi only to two decimal places. Pi is irrational â it cannot be written as any fraction of two whole numbers â so 22/7, 355/113 and 3.14 are all approximations. 355/113 is the most accurate simple one, correct to six decimal places.
How do I save the digits to a file?
Choose how many digits you want, then click 'Download as .txt'. The file is built in your browser and includes a header noting the digit count and the position convention, so nothing is uploaded anywhere.
