7ba36b5e73 fix dumb bug in input randomiser, add basic double->string benchmarks 
* input randomiser was feeding a constant value previously, now actually randomising
* start to_string with the current method (sstream), an faster more correct version (sstream_cached), snprintf, and std::to_chars
** NOTE: only std::to_chars and sstream_cached are correct in the face of locales

0adb8a69b1 add micro benchmarking project, setup number parsing benchmark 
relating to previous work https://github.com/tfussell/xlnt/issues/422
Results are matching what was observed at the time ^^ was being worked on
std::from_chars is included as the target to beat, but since only MSVC has it for floating point it's not
hugely useful yet

uniform real distribution is probably a horrible choice, and it might be good to randomise the number
of sf in each string also (currently the y all end up at max length)

Merge pull request #446 from adamhooper/issue-445 
Parse inlineStr values
 2020-02-26 13:28:46 -05:00
Adam Hooper
ac18fc6dde Parse inlineStr values 
inlineStr XML structure is <c><is><t>. This was being parsed incorrectly
when streaming (because has_value wasn't being set to true) and when
reading the whole file (because the <t> was ignored).

[closes #445]
