Numbers | Transform numbers in various formats | Code Quality library

You are running the project via Java 1.8 and add the --add-opens option to the runner. However Java 1.8 does not support it.

So, the first option is to use Java 11 to run the project, as Java 11 can recognize this VM option.

Another solution is to find a place where --add-opens is added and remove it. Check Run configuration in IntelliJ IDEA (VM options field) and Maven/Gradle configuration files for argLine (Maven) and jvmArgs (Gradle)

The math module from the standard library has a sqrt function to calculate the square root of a number. It takes any type that can be converted to float (which includes int) as an argument and returns a float.

Could you check if this works for you? The function returns a BigInt.

One potential solution is to specify the values manually for each scale, e.g.

It's possible to get the Perl behavior by using a sequence with a custom generator:

In order to achieve this goal we need to create permutation of all allowed paths. For example:

There is no general way to do this. Numbers are not strictly related to begin with and their types are even less.

While numbers.Number might seem like "the type of numbers" it is not universal. For example, decimal.Decimal is explicitly not a numbers.Number as either subclass, subtype or virtual subclass. Specifically for typing, numbers.Number is not endorsed by PEP 484 -- Type Hints.

In order to meaningfully type hint "numbers", one has to explicitly define what numbers are in that context. This might be a pre-existing numeric type set such as int <: float <: complex, a typing.Union/TypeVar of numeric types, a typing.Protocol to define operations and algebraic structure, or similar.

This is the PR where they added that feat. They didn't provide a better UI due to some performance constraints. But you can find what hooks those indexes correspond to if you go to the components tab in dev tools and inspect said component; in the hooks section, you'll have a tree of the called hooks, and for each hook, a small number at the left which is the index. You'll probably need to unfold the tree of hooks to find them.

Here's a screenshot from the linked PR

These are some of the use cases in which I explicitly use the L suffix in declaring the constants. Of course these are not strictly "canonical" (or the only ones), but maybe you can have an idea of the rationale behind. I added, for each case, a "necessary" flag; you will see that these arise only if you interface other languages (like C).

• Logical type conversion (not necessary)

Instead of using a classic as.integer, I use adding 0L to a logical vector to make it integer. Of course you could just use 0, but this would require more memory (typically 8 bytes instead of four) and a conversion.

• Manipulating the result of a function that returns integer (not necessary)

Say for instance that you want to find to retrieve the elements of the vector after a NA. You could:
