Error after calculating, the calculation returns a error even if it is mathematically correct

I have a problem making a calculation on laravel this is the calculation:

$inc = round(100*($Incom->total_amount/$TotalRewenue), 2);

I tested if $Incom is 0, $Incom->total_amount is 0 and $TotalRewenue is 0 and neather of theme are 0 and if i putt a dd of $inc i actually get the value of the calculation correct.

this is the full code:

    $TotalIncome = DB::table('actuals_report')->where('companyId',$id)->Where('dataYear',$dataYear)->where('type','LIKE','TotlaIncome%')->first();
    $TotalExpense = DB::table('actuals_report')->where('companyId',$id)->Where('dataYear',$dataYear)->where('type','LIKE','TotlaExpense%')->first();
    $TotalRewenue = $TotalIncome->year - $TotalExpense->year;



    foreach($TopTwentyIncomers as $topIncomer)
    {
        foreach($TopTwentyExpensers as $topExpenser)
        {
            if($topIncomer->name == $topExpenser->name)
            {
                $topTwentyRevenuers[] = (object) array('name' => $topIncomer->name, 'total_amount' => $topIncomer->total_amount - $topExpenser->total_amount);
            }
        }
    }

    foreach($topTwentyRevenuers as $Incom)
    {

        $inc = round(100*($Incom->total_amount/$TotalRewenue), 2);
        //dd($Incom->total_amount);
        $yearlyReportExists = DB::table('yearly_report')
            ->where('company_id', $id)
            ->where('year', $dataYear)
            ->where('client_name', $Incom->name)
            ->Where('type','LIKE','%highestGenerator%')
            ->first();

        if(!empty($yearlyReportExists)){
            DB::table('yearly_report')
                ->where('id', $yearlyReportExists->id)
                ->update(['company_id'=>$id,'year'=>$dataYear,'type'=>"highestGenerator",'client_name'=>$Incom->name,'amount'=>round($Incom->total_amount, 2),'inc'=>$inc]);
        }
        else{
            dd($inc);
            DB::table('yearly_report')->insert(['company_id'=>$id,'year'=>$dataYear,'type'=>"highestGenerator",'client_name'=>$Incom->name,'amount'=>round($Incom->total_amount, 2),'inc'=>$inc]);
        }
    }
