# What is pi to 30 decimal places

## Pi to 100 digits

Enclosed are the first 100 decimal places of pi. If you look closely (because of the 3 in front of the decimal point), this is even one place more than you might expect according to the heading “Pi to 100 places” 😉

Interestingly enough, there is a certain demand for the front digits of Pi. For example, by all those Pi fans who would like to join the Association of Friends of the Number PI. The condition for admission is the mastery of the first 100 decimal places of Pi. You can also go further and try to memorize Pi to 1000 places or more. That falls into the area of ​​memory training or memory sports.

Of course, you can also just memorize Pi from jokes and dolls in 100 or more digits. To impress yourself and / or others. As, for example, implemented very funny in the film “Life of PI”. Or you can do it like the villager and shoot a video to celebrate Pi Day and juggle soccer balls and recite the first 200 digits of Pi.

Many people find it very difficult to memorize numbers. Numbers are in great demand not only in terms of mathematics, but also in everyday life. Postcodes, phone numbers or bank account numbers can become a real burden. With dull "numbers" you usually don't get very far. But there are also techniques that help you Memorize Numbers can be of great help.

With techniques such as the major or master system and plenty of practice, users can memorize the first 100 digits of Pi in around 5 minutes. At least that is the statement in the video above. I haven't tested it yet, but I believe in the advantages of such systems. I've been gurgling for hours with the blunt numbers. And only got to 100 digits.

Sometimes the question of the frequency distribution of the digits of Pi is also asked. For the 100 + 1 digits shown above, the distribution is as follows:

 Number of digits for the first 101 digits of Pi Digit 0 1 2 3 4 5 6 7 8 9 frequency 8 8 12 12 10 8 9 8 12 14

Purists will only want to know the answer for 100 digits instead of 101 digits, especially because some tables on the web also list this variant. For example Eve Andersson, who lists various frequencies (100, 1000, 10,000, 100,000, 1,000,000 and 10,000,000) and also illustrates them in bar form.

 Number of digits for the first 100 digits of Pi Digit 0 1 2 3 4 5 6 7 8 9 frequency 8 8 12 12 10 8 9 8 12 13

Incidentally, the majority of mathematicians believe that the number pi normal is what, among other things, would result in the same frequencies for all of its digits. All digits would be equally likely. A look at the frequency of digits at Gerd Lamprecht clearly shows this head-to-head race of the digits of Pi.

Finally, now again the 100 digits of Pi in a musical way:
