Summary|log for Complex |Missing functions in
| |std.complex
--- Comment #1 from Simen Kjaeraas <simen.kja...@gmail.com> ---
Not just log, either - all of the following functions are missing:
acos, acosh, approxEqual, asin, asinh, atan, atan2, atanh, cbrt, ceil,
copysign, cosh, exp, floor, isInfinity, isNaN, log, log10, log2, poly, pow,
round, sgn, sinh, tan, tanh, trunc.
Naïve implementations of every one of those are available here:

There's probably plenty of optimization opportunities, as very little attempt
has been made to make the functions fast, but they should provide a starting
point for anyone wanting to make something better.
There are other functions in std.math that might make sense to implement for
complex numbers, like remainder, scalbn, exp2, expm1, ldexp, quantize, and
hypot.
