We present Ryū, a new routine to convert binary floating point numbers to their decimal representations using only fixed-size integer operations, and prove its correctness. Ryū is simpler and approximately three times faster than the previously fastest implementation.

It is shown that both Ryū and Ryū Printf generalize to arbitrary number bases, which implies the existence of a fast algorithm to convert from base-10 to base-2, as long as the maximum precision of the input is known a priori.

By combining the significand and precomputed tables, the solution to the problem of parsing decimal numbers to the nearest binary floating‐point value can be several times faster than conventional functions present in standard C libraries on modern 64‐bit systems.
Grassland: A Rapid Algebraic Modeling System for Million-variable Optimization
Grassland is a rapid AMS that provides an end-to-end solution to tackle emerged new challenges, and integrates a parallelized instantiation scheme for large-scale linear constraints, and a sequential decomposition method that accelerates model solving exponentially with an acceptable loss of optimality.


Easy Accurate Reading and Writing of Floating-Point Numbers
Presented here are algorithms for converting between (decimal) scientific-notation and (binary) IEEE-754 double-precision floating-point numbers by employing a rounding integer quotient operation, which execute as fast or faster than Java's native conversions over nearly all of the IEEE-753 double- Precision range.
