%description
Dragonbox is a float-to-string conversion algorithm.

It generates a pair of integers from a floating-point number: the decimal
significand and the decimal exponent of the input floating-point number.
These integers can then be used for string generation of decimal
representation of the input floating-point number, the procedure
commonly called ftoa or dtoa.

The algorithm guarantees three things:

1. It has the roundtrip guarantee; that is, a correct parser interprets the
   generated output string as the original input floating-point number.

2. The output is of the shortest length; that is, no other output strings that
   are interpreted as the input number can contain less number of significand
   digits than the output of Dragonbox.

3. The output is correctly rounded: the number generated by Dragonbox is the
   closest to the actual value of the input number among possible outputs of
   minimum number of digits.
