Enter Vim clean-sheet (vim -u NONE) and write the following text:

a a
a
a

Go to the beginning of the file, search for a, go back to the first result and do a search/replace with a*, repeating it once:

gg*Ncgna*<Esc>.

If you have a number x of the form:

a.bc

Where a is the integer part, b is the non-repeating fractional part, and c is the repeating fractional part, then the resulting fraction has value:

a.b + c / ((10^num_digits(c) - 1) * 10^num_digits(b))

So for 0.333333... we have:

	#include <cstdint>

	// Random 32-bit unsigned integer.
	uint32_t pcg32(uint64_t& rng) {
	rng = rng * 6364136223846793005ULL + 1;
	int rot = rng >> 59u;
	uint32_t r = (rng >> 18u) ^ rng;
	return (r >> rot) \| (r << (32 - rot));
	}

	Install VS2015 Express, Mercurial and `hg clone https://hg.python.org/cpython`.

	Patch cpython/PC/python_ver_rc.h (why is this necessary?):
	- # include <pythonnt_rc_d.h>
	+ # include <pythonnt_rc.h>

	cd cpython/PCbuild
	get_externals
	build -d -c Debug
	build -c Release
