Hello,

I am not a C++ expert nor a unreal engine expert but for now 6 month I am trying to prototype an application I would like to use to work with advertising agency ...there is a lot to do about virtual products...but I need some advanced options.

So I'd try first with blueprint and discover the float/double precision problem...then I try to make it in C++ but it's much more complicated for me as you can consider me as an "artist" and not a programmer. I also tried to use math expression too but some of my data are like 0.000000000875 and so in float the result is 0 which is not possible...and multiply the value by 1000000 then divide the result is not possible as the algorithm is very complicated.

also small bug ? math expression can't start with a negative value like -2.79....

So...to make it shorter : I can see that you would like Architect, Enterprises, Engineers to use more UE4 but I think they also need double precision ... at least to make calculation and then convert the result to float if there is no other solution. So please can you do something here ? And if there is already a solution please make it more visible because after hours of search on the web I didn't find a solution...all I find is obsolete or useless

This said I love UE4.Thanks !
