BMOD | BMOD - Extended Physics Module | Game Engine library

https://metacpan.org/pod/Math::BigInt#Arithmetic-methods : "These methods modify the invocand object and returns it." In other words, bmod, bsub, and badd are like %=, -=, and +=, not like %, -, and +.

So everywhere where you call one of the arithmetic methods, you should copy first, so the object you are currently calling the method on isn't changed:

Not the best approach, but may help you to figure out a better solution

No, this is not possible. Your module type C would be recursive, which is not allowed. Such a form of recursion could very easily lead to undecidable type checking, given the expressive power of module types.

It seems like you are trying to shoehorn an object-oriented pattern onto modules, which won't usually work -- ML modules are very much a functional language in nature. What's wrong with the following?

There's a couple of problems with your script, which is natural for a beginner, so don't get disheartened.

Missing semi-colon

On line 8 of your Javascript you don't end your lie with a semicolon. I believe this isn't a critical issue in Javascript, but it's certainly good practice.

Missing var

In your for loop you use the variable i without declaring it first (var). This means i is declared in the global scope, which can lead to unexpected behavior.

Treating aMod and bMod as integers, not arrays

Your variables aMod and bMod are arrays, not integers. In order to compare them to i you need to compare their .length

You have included a return statement which breaks program flow

You only need a return statement if you're returning a value to be used later on. Since the function merge() assigns the value c to the element output in it's final line, you don't need the return statement.

getElementById is case sensitive

In your final line you have written getElementbyId not getElementById (note the letter B)

You are assigning the value "c" not the variable c

Also in your final line, you are assigning the string value "c" to your element output, not the variable c.

In summary, this code demonstrates the changes above:

Don't define the class inside a function. Just define the Base in a single definition module then import that module from the other modules:

db.py

There are some ways to do this:

• Since you extends JPanel and have GridBagLayout for the whole panel, you could just add additional row for buttons. It looks like table layout in Web - and it actually is. There are pro and contras with table layout. The main disadvantage is it's hard to mantain in a long-term project. In particular, you can't re-use buttons elsewhere.
• You could create additional panel with buttons, as @Izruo suggested. The key feature is you could easily move this panel from bottom to left of your grid, add to another similar panel/menu etc. The simplest FlowLayout would be enough. After you created a ButtonPanel, you could
  • add it to your grid. It's slightly better than table-only layout
  • create CompositePanel which will contain both GridPanel and ButtonPanel

Studying Oracle tutorial I noticed that the last option is preferable. From my personal experience, it's a best practice
