What's the lowest bits precision when the total bits are less than 16?
CREATE TABLE table_54790 (
    "Type" text,
    "Sign" real,
    "Exponent" real,
    "Significand" real,
    "Total bits" real,
    "Exponent bias" real,
    "Bits precision" real,
    "Number of decimal digits" text
)
SELECT MIN("Bits precision") FROM table_54790 WHERE "Total bits" < '16'
