π, e, ln(2) & ln(10) CalculatorImage of new icon

Need to know π, e, ln(2) & ln(10) with thousands or millions of digits. This is the place to go to calculate these transcendental constants with unlimited precision. Calculating π, e or ln(2) or ln(10) is implemented based on the Spigot algorithm to any number of digits, see the authors paper on this subject.

The Transcendental constant of π, e, ln(2) & ln(10)

Calculate the Digits of π, e or ln(2) or ln(10) based on the Spigot algorithm to any number of digits, see the author´s paper on this subject. The field Digits is the requested number of digits of one of the transcendental constants. The progress bar doesn't work since it cannot automatically been updated while doing the time-consuming calculation of π, e, ln(2), or ln(10). Please note that calculating π with 65000 digits takes around 10 min on my PC while 1000 digits are less than a second.
Be careful not to set the number too high since it will take a while. Also, notice that ln(10) is significantly slower to calculate than ln(2).

Corrections:
28-Feb-2022 Vs 1.5 Cosmetic change for better mobile usability
30-Oct-2019 Vs 1.4 Redesign internal GUI functions
28-Jan-2017 Vs 1.3 Dramatically improve the performance of LN(10). Now max twice the time for an LN(2) calculation. Prior to this improvement the LN(10) was 5-7 times slower than an LN(2) calculation
26-Jan-2017 Vs 1.2 Added Calculation of LN(10)
25-Dec-2016 Vs 1.1 Added Calculation of LN(2)
25-Nov-2016 Vs 1 Initial release, calculating the transcendental constants π & e
