When converting floats to string, we now enforce the "C" locale, so decimal points will be written as "." rather than the "," separator used natively in some European locales. Also, we now use operator>> to read back the number instead of std::stof. std::stof works in the system locale, and will fail to read back floats with the wrong decimal separator. (Also, std::stof will throw if the number is out of range and can't fit in the destination, which implies that the `if` check was probably never failing.) Skia encountered similar issues: see http://review.skia.org/587536 for the Skia implementation.

Dawn, a WebGPU implementation
Dawn is an open-source and cross-platform implementation of the work-in-progress WebGPU standard.
More precisely it implements webgpu.h that is a one-to-one mapping with the WebGPU IDL.
Dawn is meant to be integrated as part of a larger system and is the underlying implementation of WebGPU in Chromium.
Dawn provides several WebGPU building blocks:
- WebGPU C/C++ headers that applications and other building blocks use.
- The
webgpu.hversion that Dawn implements. - A C++ wrapper for the
webgpu.h.
- The
- A "native" implementation of WebGPU using platforms' GPU APIs: D3D12, Metal, Vulkan and OpenGL. See per API support for more details.
- A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
- Tint is a compiler for the WebGPU Shader Language (WGSL) that can be used in standalone to convert shaders from and to WGSL.
