CREATE TABLE table_9641 ("Morse Taper number" FLOAT, "Taper" TEXT, "B  ( max ) " FLOAT, "C  ( max ) " FLOAT, "D  ( max ) " FLOAT)

What is the minimum D (max) when the Morse Taper number is less than 0?
SELECT MIN("D (max)") FROM table_9641 WHERE "Morse Taper number" < '0'
SELECT MIN("D (max)") FROM "table_9641" WHERE "Morse Taper number" < '0'
