Walter has been adamant that we should always compute std.math.* functions with the `real` type, which on x86 maps to the non-IEEE 80-bit floats. However, 80-bit floats have been deprecated for a while now, and pretty much nobody cares to improve their performance on newer CPUs, focusing instead on SSE/MMX performance with 64-bit doubles. People have been clamoring for using 64-bit doubles by default rather than 80-bit floats, but so far Walter has refused to budge.
I wonder if Ilya has worked on any of this for Mir.
