CRC Functions
AMPS includes functions that compute a CRC checksum over a string. This function is useful for creating a numeric identifier from a string representation. This is commonly-used to create a shortened representation of the string, or to provide input for a MOD calculation.
CRC32
string
Returns an integer calculated as a checksum of the provided string.
This function returns a 32-bit integer.
If a NULL value is provided, this function returns a constant value.
This function uses CRC32-C to create the result.

CRC64
string
Returns an integer calculated as a checksum of the provided string.
This function returns a 64-bit integer.
If a NULL value is provided, this function returns a constant value.
This function uses a polynomial of 0x95AC9329AC4BC9B5 to create the result.
