return negative value of hexa decimal value - Typescript

I am trying to store a enum value with a hexadecimal number expecting it to store a negative value. But it always returns positive value. How do i extract the negative value from the stored enum value?

const enum MyErrorCode {
unAuthorizedError = 0x80040226
}

If i do a console print for unAuthorizedError, it gives me 2147746342, but i am expecting to get -2147220954 (Decimal from signed 2's complement). How do i achieve this?

The reason why i needed this is i have a central repository where i stored all the codes in negative numbers and in order to compare that error code in my current scenario i am using the hexa decimal stored in enum and comparing it which is always giving me false given the negative and positive differences.
