Just Import Numbers.

```python

>> 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](#how-to-test), and uses [sympy](https://pypi.org/project/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

```
