sin
still seems very slow and still allocates:
julia> x = interval(0, 1)
Interval(0.0, 1.0)
julia> @btime sin($x)
854.841 ns (14 allocations: 448 bytes)
Interval(0.0, 0.8414709848078966)
from intervalarithmetic.jl.
Most of the time seems, unfortunately, to be being spent in doing
x / half_pi(Float64)
for x::Float64
. This calls convert(Interval, x)
, which is slow. :/
Perhaps we should add explicit methods for x / Y
for float x
and interval Y
, which just wrap x
into Interval(x)
.

Closing, since it is already fixed.
