Add a `copysign` function to f32 and f64 2018-10-18T01:15:00+00:00 Raph Levien raph.levien@gmail.com 2018-10-18T01:15:00+00:00 urn:sha1:0e6c3f29be98176c91aa77eb71c04cca18c51115 This patch adds a `copysign` function to the float primitive types. It is an exceptionally useful function for writing efficient numeric code, as it often avoids branches, is auto-vectorizable, and there are efficient intrinsics for most platforms. I think this might work as-is, as the relevant `copysign` intrinsic is already used internally for the implementation of `signum`. It's possible that an implementation might be needed in japaric/libm for portability across all platforms, in which case I'll do that also.
