charc_math

This started out as a private collection of maths functions, many quite simple. Over time I've accumulated quite a few, and I thought it should be shared. Nothing is too complicated - I hope.

tl;dr Maths functions.

Code Example

import charc_math as c

print c.primes(10):
#Output [2, 3, 5, 7]

Motivation

Each function here has at some point been written and used by me to solve various maths problems, from ProjectEuler, to PythonChallenge, to my own recreational maths work.

Installation

sudo pip install charc_math

import charc_math
# as you normally would...

Tests

Each one has gone through testing before finally being put into this proper collection. If you find any bugs contact me at the email provided and I'll look into it.

def test_primes():
	assert_equal(primes(100),[2,3,5,7,11,13,17,19,23,29,31,37,41,43,47,53,59,61,67,71,73,79,83,89,97])
	assert_equal(primes(2),[2])
	assert_equal(primes(-10),[])
	assert_equal(primes(1),[])

Contributors

So far just me. I'd like to thank any of my friends who will have without a doubt readover at least one of these files just to make sure it has no typos or anything else stupid.

License

MIT. Basically I don't care what you do with the code so long as you:

don't ~~try to pass it off as your own~~ (lol, I know just how basic it is.)
give me credit

##TODO

Finish porting all of this from everywhere into one place
Work on more common maths functions
Speed - not the drug or the film
Sort out the README page
???

Contact me if you want to add more things to that list.

Known Bugs

Each bug I find is with the function, but still a general list for those unwilling to read (including me)

isAP is ~~not very numerically accurate~~ better now.
isGP is not at all numerically accurate, this needs lots of work and fixing
