Hello!
I have found that Phobos has sum, but in module std.algorithm!
refs:
std.numeric.dotProduct:
http://dlang.org/phobos/std_numeric.html#.dotProduct
std_algorithm.sum:
http://dlang.org/phobos/std_algorithm.html#.sum
Both sum and dotProduct are general purpose numeric algorithms
(yes, very trivial) with the same summation logic. The summation
method can be:
a. Strongly Serial (it needed for numeric algorithms like in
cephes(Netlib) library.)
b. Fast (with SIMD instruction or loop unrolling like in
dotProduct source code)
c. Reversed Strongly Serial
d. Reversed Fast
e. Precise (like in sum source code) There are different ways of
precise summation. For example in Julia language you can choice
an algorithm.
e.1 Precise algorithm 1
...
e.2 Precise algorithm N
So, can I make PR with that
1. realize unification in single module (std.numeric?) and logic
2. provide ability to select summation algorithm (default ==
Fast?)
Best regards,
Ilya
