17:19 Slug #1556: DivAlg slower than NR
- Check the code for NR and see how to make the data type for the output.
-
- Just for the record: @NR@ took about 0.063s, @DivAlg@ took about 1280s.
Presumably @DivAlg@ should also be built-i... -

I personally prefer the return value representing a rational a...

- I have now implemented *@ElapsedTime@* (based on the standard C++ @steady_clock@)....

- I have added a safety check. It seems to work well enough.
Tomorrow I'll check it in.

Improve it!
