2017-11-08std: Move the `cmath` module into the `sys` moduleAlex Crichton-47/+2
This commit moves the `f32::cmath` and `f64::cmath` modules into the `sys` module. Note that these are not publicly exported modules, simply implementation details. These modules are already platform-specific with shims on MSVC and this is mostly just a reflection of that reality. This should also help cut down on `#[cfg]` traffic if platforms are brought on which don't directly support these functions.

2017-07-03Make sNaN removal code tolerate different sNaN encodingsest31-5/+8
IEEE 754-1985 specifies the encoding of NaN floating point numbers, but while it mentions that NaNs can be subdivided into signaling and quiet ones, it doesn't fix the encoding of signaling NaNs in binary formats. This led to different implementations (CPUs) having different encodings. IEEE 754-2008 finally specified the encoding of signaling NaNs but some architectures are compatible with it, while others aren't. Certain MIPS and PA-RISC CPUs have different encodings for signaling NaNs. In order to have the float <-> binary cast feature of the std library be portable to them, we don't mask any quiet NaNs like we did before (only being compliant to IEEE 754-2008 and nothing else), but instead we simply pass a known good NaN instead. Note that in the code removed there was a bug; the 64 bit mask for quiet NaNs should have been `0x0008000000000000` instead of the specified `0x0001000000000000`.
2017-06-28Auto merge of #42431 - nagisa:core-float-2, r=alexcrichtonbors-18/+8
Fix NaN handling in is_sign_negative/positive This would be my proposed fix for the #42425 provided we decide it is indeed a problem. Note this would technically be a breaking change to a stable API. We might want to consider deprecating these methods and adding new ones.

2016-11-01std: Flatten the num directory to reflect the module layoutBrian Anderson-0/+1756
This makes it dissimilar to how core is structured on disk, but more predictable on its own.
