Comment(by wcauchois):
Incorporating the time it takes to call fast_float, the speedup is not
that radical:
{{{
sage: var('x')
x
sage: from sage.ext.fast_eval import fast_float
sage: timeit("find_root(sin(x)-cos(x), 0, pi)")
625 loops, best of 3: 441 µs per loop
sage: timeit("find_root(fast_float(sin(x)-cos(x), x), 0, pi)")
625 loops, best of 3: 393 µs per loop
}}}
Its better for clients to call fast_float themselves, if they're using
find_root inside a loop.
