WebThe FLOAT data type is a floating-point number with a binary precision b. The default precision for this data type is 126 binary, or 38 decimal. The DOUBLE PRECISION data type is a floating-point number with binary precision 126. The REAL data type is a floating-point number with a binary precision of 63, or 18 decimal.
