Date: Mon, 9 Apr 2012 15:17:12 -0400 From: Rich Felker <dalias@...ifal.cx> To: musl@...ts.openwall.com Subject: float scanner status, upcoming release Hi all, My recent work on musl has mainly been writing the new floating point scanning code for strtod, scanf, etc. The existing code in musl is essentially just a placeholder; its results were seriously inaccurate in all but the most trivial usage cases. Unfortunately, getting accurate results, especially if you want them correctly rounded for the current rounding direction, destination floating point precision, and denormal corner-cases, is highly non-trivial and involves high-precision arithmetic. At this point, the new implementation is essentially done, but lacking integration with libc; it's just a standalone program for reading decimal floating point strings and converting them. Integration will require a bit more work getting the function interface suitable for use by both *scanf() and strto*()/wcsto*(), along with general cleanups and implementing the now-missing (but MUCH easier) hex float support. I'll keep working on it as time allows, and hope to have it committed within the next few days. At that point I'm hoping to release 0.8.8, so please report any other pending issues that should be fixed before release. Rich
