Question: What's the lowest bits precision when the total bits are less than 16?
Columns: ['Type', 'Sign', 'Exponent', 'Significand', 'Total bits', 'Exponent bias', 'Bits precision', 'Number of decimal digits']
Types: ['text', 'real', 'real', 'real', 'real', 'real', 'real', 'text']
Sample row: ['Half ( IEEE 754-2008 )', 1.0, 5.0, 10.0, 16.0, 15.0, 11.0, '~3.3']
SQL:

assistant: SELECT MIN("Bits precision") FROM "Table" WHERE "Total bits" < 16.0;
