This extension is to show math (Unicode) for F# program. this is a requirements from F# user published on Visual Studio connection:
So instead of saying
let inline (!++) xs = xs |> Seq.sum
you could say
let inline (~∑) xs = xs |> Seq.sum
Writing "∑myList" is much, much easier on the eyes and brain than trying to figure out what "!++myList" does.
this addon is to solve this problem.
this addon needs a mapping file, please see detailed information at http://apollo13cn.blogspot.com/2012/09/math-unicode-symbol-add-on-for-f.html.
