This library is a reference implementation of Dragonbox in C++. Dragonbox is a float-to-string conversion algorithm based on a beautiful algorithm Schubfach, developed by Raffaello Giulietti in 2017-2018. Dragonbox is further inspired by Grisu and Grisu-Exact. Dragonbox 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 the decimal representation of the input floating-point number, the procedure commonly called ftoa or dtoa.
Features
- It has the roundtrip guarantee; that is, a correct parser interprets the generated output string as the original input floating-point number. (See here for some explanation on this
- 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
- 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
- Include Dragonbox into CMake project
- Documentation available
- Examples included
