floating | Positioning and Floating Elements | Android library

I am aware that floating-point numbers are tricky. But today I encountered a case that I cannot explain (and cannot reproduce using a standalone C++ code).

The code within a large project looks like this:

I am trying to get the Coriolis matrix for my robot (need the matrix explicitly for the controller) based on the following approach which I have found online:

Will I possibly loose any decimal digits (precision) when multiplying Number.MAX_SAFE_INTEGER by Math.random() in JavaScript?

I presume I won't but it'd be nice to have a credible explanation as to why 😎

Edited, In layman terms, we're dealing with two IEEE 754 double-precision floating-point numbers, one is the maximal integer (for double-precision), the other one is fractional with quite a few digits after a decimal point. What if (say) I first converted them to quadruple-precision format, then multiplied, and then converted the product back to double-precision, would the result be any different?

The documentation for convertMaps says that it supports the following transformation:

(CV_32FC1, CV_32FC1)→(CV_16SC2, CV_16UC1) This is the most frequently used conversion operation, in which the original floating-point maps (see remap) are converted to a more compact and much faster fixed-point representation. The first output array contains the rounded coordinates and the second array (created only when nninterpolation=false) contains indices in the interpolation tables.

I understand that (CV_32FC1, CV_32FC1) is encoding (x, y) coordinates as floats. How does the fixed point format work? What is encoded in each 2-channel entry of the CV_16SC2 matrix? What interpolation tables does the CV_16UC1 matrix index into?

I have a html file with a ng-template modal box defined like this

How to change color of floating action button on theme change ? in flutter and also How can I find out what the current theme is in the app? in flutter

I'm trying to show all user posts that the user who is using the app follows, and I'm using Firestore. I take all the ids and put them on an arraylist and build a query. I am using FirebaseRecyclerView but I have this error:

Similar questions to this have been asked many times, but surprisingly few of the answers seem to address what I believe my problem to be.

I have csv files with one or more columns that contain a dictionary in each cell. After read_csv step, I have tried ast.literal_eval on these columns in order to convert the str format dicts into dict type objects. However, I keep getting the malformed node or string error.

Here is a typical example of the dicts in question: {1: 3681.45, 0: 3693.3333333333335}. And another, with a nan value: {1: 4959.95652173913, 0: nan}. Edit: It was only this nan value causing the error, in fact (see Rakesh's solution below).

Looking through previous answers, one reason for this error may be because most of the values of the dicts in these columns are floating point numbers, and apparently literal_eval can't handle floats or nans, even if they're contained within dictionaries (although, this is me inferring from a question about tuples).

I had to read a lot of questions and answers even to get this much information, so thought it could be useful to start a new topic with the keywords str, dict, but also nan in the title.

Any help much appreciated!

In my game I want to have a floating monster that's attack throws a grenade at the player. My problem is that the grenade only spawns in 0, 0, 0. In my script I make it so that the zombies spawns in on its own location but for some reason that doesn't work. I tried making it spawn by having the spawn location equal new Vector3(100, 100, 100) but it still spawned at 0, 0, 0. I know that the co-routine runs because I put a Debug.Log. Thanks for the help!

Edit #2: I can't have a rigidbody on the script. I have edited the movement script and I have found that no mater what if a rigidbody is added then it will go to 0, 0, 0.

Edit #3: I updated the scripts

Here is my script: (Sorry if the code is bad)
