This might help you This is my code: , Your first job is to replace
code :
const int MAX_LITERS_OF_MILK_PER_CARTON = 3.78;
const double MAX_LITERS_OF_MILK_PER_CARTON = 3.78;
totalProfit = litersOfMilk * PROFIT_PER_CARTON / MAX_LITERS_OF_MILK_PER_CARTON;
std::round(actualNumberOfCartonsNeeded)
static_cast<int>(actualNumberOfCartonsNeeded + 0.5);

Avoid signed by unsigned integer division

fixed the issue. Will look into that further I ran into this problem when I was doing the following code: , gcc has the -Wconversion flag, which for this case warns me:
code :
warning: conversion to ‘int’ from ‘std::vector<int>::size_type {aka long unsigned int}’   may alter its value [-Wconversion]
     int average = std::accumulate(vi.begin(), vi.end(), 0) / vi.size();
                                                            ^

How to avoid integer overflow in case of pow function in division with a number?

Hope this helps I don't have time to write a proper answer now; I'll expand this later if I get a chance. The basic idea is to use the grade-school algorithm, working with "digits" that are a power of the denominator. Do a Google search for "Schrage multiplication" or look here for references.

Warn about or avoid integer division (resulting in truncation) in scala

I wish this helpful for you To the best of my knowledge, the Scala compiler does not seem to provide a warning flag that could allow you to raise a warning (documentation here).
What you could do, however, if you find the effort worth it, is using Scalafix and write your own custom rule to detect integer divisions and report warnings about it.
code :
import scalafix.lint.{Diagnostic, LintSeverity}
import scalafix.patch.Patch
import scalafix.v1.{SemanticDocument, SemanticRule}

import scala.meta.inputs.Position
import scala.meta.{Lit, Term}

class IntDivision extends SemanticRule("IntDivision") {

  override def fix(implicit doc: SemanticDocument): Patch =
    doc.tree.collect({
      case term @ Term.ApplyInfix((_: Lit.Int, Term.Name("/"), Nil, _: List[Lit.Int])) =>
        Patch.lint(new Diagnostic {
          override final val severity: LintSeverity = LintSeverity.Warning
          override final val message: String = "Integer division"
          override final val position: Position = term.pos
        })
    }).asPatch

}
object Main {
  def main(args: Array[String]): Unit = {
    println(1 / 2)
  }
}
[warn] /path/to/Main.scala:3:13: warning: [IntDivision] Integer division
[warn]     println(1 / 2)
[warn]             ^^^^^

Integer modulus division and integer division remainder with Ballerina

Any of those help You can get the modulus by using / operator and remainder using % operator.
Check the following code:
code :
import ballerina/io;

public function main() {
    int i = 10;
    int j = 3;

    int x = i / j;
    int y = i % j;

    io:println("i / j = " + x.toString());
    io:println("i % j = " + y.toString());
}
i / j = 3
i % j = 1

How to avoid integer division warning?

it should still fix some issue You can turn off specific warnings using the form -Wno-[warningname]. Any warnings that are not specifically negated are still reported. For your case, you can use:
