That's by DMD32 on Windows. (Sorry, my DMD64 broke after
upgrading Visual Studio to 2017, and I failed to fix it right

general purpose floating-point hardware, right?)
Boy do I ever have some bad news for you!
SSE for 64bit and x87 for 32bit, as per run.dlang.org.
Wow, thanks!
As per https://run.dlang.io/, it's fast for float and double, but
slow for reals (which are 80 bits and don't fit into the fancy
instructions you mention). Unfortunately, it fails to compile
with -m32, but anyway, point taken.
As an aside, learning something new after virtually every post is
why I love the D forum/newsgroup.
