kandi X-RAY | imath Summary
IMath is a library written in portable ISO C that allows you to perform arithmetic on integers and rational numbers of arbitrary precision. While many programming languages, including Java, Perl, and Python provide arbitrary precision numbers as a standard library or language feature, C does not. IMath was designed to be small, self-contained, easy to understand and use, and as portable as possible across various platforms. The API is simple, and the code should be comparatively easy to modify or extend. Simplicity and portability are useful goals for some applications—however, IMath does not attempt to break performance records. If you need the fastest possible implementation, you might consider some other libraries, such as GNU MP (GMP), MIRACL, or the bignum library from OpenSSL.

QUESTION
I'm a newbie in JavaFX, trying to start with a windowed application. For start I have a simple ComboBox and I'm filling it with game types, to choose one. Nothing more for start. And there problem begins. According to this answer I have created a model class for entering values in a ComboBox. However, when application starts, there is an error:
ANSWER
Answered 2021-Aug-15 at 05:25When Combobox is initialized and no value is selected the object in public String toString(GameType object) is null.
public String toString(GameType object) has to be modified to handle null object.
For example:
QUESTION
I am trying to solve a system of equations. The equations in the example below are the first derivatives of a Lagrangian function (LDash 1 through 7), which I obtained by pen and paper. The solutions to the system should give the candidates for maxima and minima.
The choice variables are X1, X2, LC, LA, s, u, while all other symbols are place holders for positive reals.
The script runs but then doesn't display anything in my console. In the examples throughout the SymPy documentation solve outputs the solution. Can you help me find out why it does not do that in my example below?
I am completely new to Python, so please let me know how I can improve. Thanks!
...ANSWER
Answered 2021-Jun-17 at 12:37You have two problems, firstly the solve call will take a very long time and potentially not return successfully at all. Secondly even if it would return, say you replace the call with solve(LDash1, X1) the return value of solve is never printed. Try to replace the last line with this for example to be able to debug your equations

QUESTION
I am trying to get blender render depth map of an object and then moving it to overlay the original object. Currently I have no issue with rendering the object and extracting it into it's place.
However, I am stuck when trying to position the object into it's original position.
I'm trying to apply inverse camera world matrix to the rendered pointcloud (in blue). Unfortunately, when I apply said camera inverse it doesn't appear nowhere near where I'd expect (in red).
I have attached the entirety of code that I have to replicate this behaviour. I would appreciate it if someone would point me to the right matrix that I should be multiplying the point cloud by.
...ANSWER
Answered 2020-Nov-25 at 15:17The problem was compound, first I needed to replace my transformed vertex calculation from instead using inverse camera world matrix, to negatively scaled camera world matrix like so

I want to use OpenEXR in a Bazel project.
My WORKSPACE.bazel look like this:
...ANSWER
Answered 2020-Oct-04 at 19:17In the meantime, I was able to solve the problem. Base on the BUILD file file from seurat I took an up to date master version von OpenEXR and started to fix all issues. The final BUILD.bazel was tested successfully with Ubuntu 16.08 GCC, LLVM and Windows 10 VS2019.
I created my own bazel branch for the OpenEXR: https://github.com/Vertexwahn/openexr/tree/bazel

const mathsFunction = returnNewobj(maths, "mathsFunction");
mathsFunction. // it doesn't suggest the function inside the mathsFunction
ANSWER
Answered 2020-Aug-24 at 10:22You need to make returnNewobj generic in order to forward the type of the target object to the result:
