What's the sum of sign with more than 53 bits precision, double extended (80-bit) type, and more than 80 total bits?
CREATE TABLE table_54789 (
    "Type" text,
    "Sign" real,
    "Exponent" real,
    "Significand" real,
    "Total bits" real,
    "Exponent bias" real,
    "Bits precision" real,
    "Number of decimal digits" text
)
SELECT SUM("Sign") FROM table_54789 WHERE "Bits precision" > '53' AND "Type" = 'double extended (80-bit)' AND "Total bits" > '80'
