For this MySQL table:
NOTE the colums float2 and float2_1:
CREATE TABLE float_table(description TEXT,
col_float_unsigned float unsigned,
col_float0 float(0),
col_float1 float(1),
col_float2 float(2,0),
col_float2_1 float(2),
col_float float,
col_float_5_2 float(5,2),
col_float_23 float(23,1),
col_float_not_null float NOT NULL,
col_float_default_null float DEFAULT NULL,
col_float_default float(5,2) DEFAULT 999.99
) ENGINE=MyISAM;
We get this Drizzledump output:
NOTE how we lost precision information for float0,float1, and float2_1.
