Link: How to print floating-point numbers

A description of how Dragon 2 (the floating point printing algorithm that Python uses) works.

It can be summarized as follows:

1. find $x$ such that $v^{\prime }=v\cdot 10^{-x}<2^p$ holds
2. print the integer part $k$ of $v^{\prime }$
3. print a decimal point
4. compute the remaining precision $n=p-\text{ceil}({\log }_2(k))$
5. print the fractional part with a precision of $n$ (this prints the integer $F$)
6. print $\cdot 10$
7. print $x$ as an exponent
