Здесь у меня есть 2 массива UInt64: 

UInt64[] debit = { 1227472838000, 239613677000, 1280855526000, 235973794000, 916401761000, 778857860000, 613860937000, 323570932000, 1379077243000, 748734870000, 319293438000, 266363662000, 962885150000, 1386950860000, 24497296322000, 1497287074000, 371579620000};

UInt64[] credit = { 1227452838000, 239613641000, 1235410585000, 235973795000, 916342194000, 778887860000, 613859937000, 323660931000, 1379080221000, 748734871000, 319293436000, 200648963000, 962885151000, 1430250860000, 16577296322000,1446583769000, 371579628000};

когда я запускаю этот код: 

for (int i = 0; i < debit.Length; i++)
{
     Console.WriteLine($"{i+1}) Debit: {debit[i]} Credit: {credit[i]}");
     Console.WriteLine($"Debit - Credit = {debit[i] - credit[i]}");
     Console.WriteLine($"Credit - Debit = {credit[i] - debit[i]}");
     Console.WriteLine("==============================================");
}

Я получаю это:

Измените часть декларации на 

    Decimal[] debit = { 1227472838000, 239613677000, 1280855526000, 235973794000, 916401761000, 778857860000, 613860937000, 323570932000, 1379077243000, 748734870000, 319293438000, 266363662000, 962885150000, 1386950860000, 24497296322000, 1497287074000, 371579620000 };

    Decimal[] credit = { 1227452838000, 239613641000, 1235410585000, 235973795000, 916342194000, 778887860000, 613859937000, 323660931000, 1379080221000, 748734871000, 319293436000, 200648963000, 962885151000, 1430250860000, 16577296322000, 1446583769000, 371579628000 };
