lofty | A dynamic DSL for building complex objects in Scala

CSS overflow:scroll; property doesn't provide large scrolling depth. Unable to see the hidden data as scrollbar doesn't scroll enough.

I want different values from the nested schema. How can I populate them so that every field is showing me its nested data and not the object ID? I'm using MongoDB and node/express.

This is my postDB where the post schema is defined:

I am currently in the process of turning a rather lofty Excel sheet that is used for calculating scientific values into a C# application. However, I am hitting some problems in regards to the rounding.

All of my values are stored as doubles, and when you perform a small number of operations on them they match the excel sheet within acceptable accuracy (5 or 6 decimal places). When they are put through rather large operations with division, multiplication, square roots. They start to drift off by quite a large margin. I switched the entire code base to decimals at another point to test if it resolved this issue, it lessened the gap but the issue still remained.

I am aware this is due to the nature of decimal numbers in software development, but it's imperative I match excels rounding as much as possible. Research on this topic points me towards the standards that excel uses to round and it seems C# by default uses a slightly different one. Despite learning of this I am still unsure of how to proceed on replicating excels rounding. I'm wondering if anyone has any advice or previous experience on this topic?

Any help would be greatly appreciated.

EDIT : I would just like to clarify that I am not rounding my numbers whatsoever. The rounding on both the sheet and my code is implicitly being applied. I have tested the same formulas inside of a totally different software package (A form builder called K2). The resulting numbers match my c# application so it seems excels implicit rounding differs in some way.

One of the offending formulas:

I am working on a project to have multiple paths representing routes a map. I am following this d3 nest example group my data by a key to create multiple routes.

I would like to animate a circle element to transition along each separate route path. I can see that my problem is very much like this example and this solution but I don't understand how to apply the solution to my example.

I can’t understand how to get the index / key of my groups into the createPathTween function. So I have just one circle element on the first of my groups rather than a circle element transitioning along each route /path. Can someone please help me work out how to place the transitioning circle element on each route path?

This is my d3 code
