• Fast string parsing
• Special ToString and ToStringBuilder methods
• Supports constant BadValue for all types
• Fully compatible with native types Int32 and Double
• Almost fully compatible with nullable types Int32? and Double?
• Universal, save, and easy to use

• SSTypesLT
• Performance
• Durability
• Practical Implementation
• Acknowledgments

SSTypesLT is C# solution with tests and examples.

Documentation

The significant performance gain was achieved for string parse operations. ToString methods still require optimization.

Performance was measured by PerfDotNet. See PerfDotNet for details.

** Test environment for the tests performed **

BenchmarkDotNet=v0.9.1.0
OS=Microsoft Windows NT 6.1.7601 Service Pack 1
Processor=Intel(R) Core(TM) i7-3610QM CPU @ 2.30GHz, ProcessorCount=4

** String Parse for Double and SmartDouble **

        Method |        Median |     StdDev |

------------------ |-------------- |----------- | Parse_Double | 2,233.6640 us | 37.0084 us | Parse_SmartDouble | 576.6582 us | 9.8574 us |

** String Parse for 9-digit Int32 and SmartInt numbers **

             Method |     Median |    StdDev |

----------------------- |----------- |---------- | Parse_Int_9_Digit | 16.3008 ms | 0.2596 ms | Parse_SmartInt_9_Digit | 3.4532 ms | 0.0471 ms |

Durability is assured by unit tests included into solution.

The solution has been successfully used in GoMap.Az project. Data workflow load includes about 10 billions string-to-double parsing operations per day.
