rust/src/libcoretest/num/dec2flt/mod.rs, branch 1.12.0

Enable unit tests for literals that overflow. I have no idea why this condition was ever added.

Prevent the immediate panic uncovered by #31109 and add a test.

The code there still triggers an ICE, but for different reasons (const eval unwraps the parse result).

Make float parsing "." return Err

2016-01-04T18:23:33+00:00

This makes both of the following return Err: ".".parse::() ".".parse::() This is a [breaking-change], which the libs team have classified as a bug fix.

Reject "+" and "-" when parsing floats.

Fixes #29042

core: Shuffle around float parsing

2015-08-18T02:35:52+00:00

Stop using stability to hide the implementation details of ParseFloatError and instead move the error type into the `dec2flt` module. Also move the implementation blocks of `FromStr for f{32,64}` into `dec2flt` directly.

Mention that the fast path is broken without SSE.

Accurate decimal-to-float parsing routines.

This commit primarily adds implementations of the algorithms from William Clinger's paper "How to Read Floating Point Numbers Accurately". It also includes a lot of infrastructure necessary for those algorithms, and some unit tests. Since these algorithms reject a few (extreme) inputs that were previously accepted, this could be seen as a [breaking-change]
