CREATE TABLE table_54789 ("Type" TEXT, "Sign" FLOAT, "Exponent" FLOAT, "Significand" FLOAT, "Total bits" FLOAT, "Exponent bias" FLOAT, "Bits precision" FLOAT, "Number of decimal digits" TEXT)

What's the sum of sign with more than 53 bits precision, double extended (80-bit) type, and more than 80 total bits?
SELECT SUM("Sign") FROM table_54789 WHERE "Bits precision" > '53' AND "Type" = 'double extended (80-bit)' AND "Total bits" > '80'
SELECT SUM("Sign") FROM "table_54789" WHERE "Bits precision" > '53' AND "Total bits" > '80' AND "Type" = 'double extended (80-bit)'
