Is it possible to use integer with a higher precision so that something like this works:

ClassMethod BigNumbers()
{
    Set bigInt1 = 9223372036854775807
    Set bigInt2 = 9223372036854775808
    W !,bigInt1
    W !,bigInt2

    Set bigInt3 = 9223372036854775807123456789
    W !,(bigInt3 # 2)
}

9223372036854775807
9223372036854775810   // should be 9223372036854775808
0                     // should be 1

The docs say ". However, with extremely large numbers (larger than 9223372036854775807E127) it is not always possible to convert a numeric string to a Decimal value.
