NumX - Import Numbers

Just Import Numbers.

>> from numx import p25  # The 25th prime
>> print(p25)
97

This library allows importing useful numbers, as the Nth prime, prime lists, random numbers, fibonacci, e, pi, ...
The library is thoroughly tested, and uses sympy as its computational mind.

How to Download

pip install numx

Supported Number Types

• pN - the Nth prime.
• plN - list of the first N primes.
• PN - count the primes upto N.
• PLN - list of primes upto N.
• nN - the number N.
• rN - random integer in range [0, N].
• piN - pi to N decimal places (as numx.__Float).
• eN - e to N decimal places (as numx.__Float).
• tN - Euler's totient function of N.
• faN - N! (N factorial).
• fiN - fibonacci(N), starting from fi0 == 0.

Moreover, for big numbers you can use:

• 2e7 to denote 2 * 10**7
• 2p7 to denote 2 ** 7
• _ as a dot, so: 6_25p_5 is 6.25 ** 0.5

An import can fail only when importing a variable written in a bad format (e.g. numx.n7e will fail).
When it fails, numx will raise the numx.__NumXError exception, which inherits from ValueError.

numx.__Float is sympy.Float, which supports the str() and float() functions.

How to Test

The library is thoroughly tested. If you want to run the test, just run:

>> git clone https://github.com/tomhea/numx.git
>> pytest numx
