Ah, thanks for digging that up. I was not aware that they didn't support fractions in exponents; I don't think I had ever tried them for that. Luckily they do give warnings, though only if you have already set the precision (via "bc -l" or something like "10 k" in dc). Sadly, since dc doesn't have a math library, it looks like you can't use the "e" function workaround unless you implement it yourself.
