Web11 apr. 2024 · Two approaches are possible: 1) a conservative approach using the largest data type (e.g., ‘int64’, ‘string’, etc., instead of dictionary), 2) an adaptive approach that modifies the schema on the fly based on the observed cardinality of the field (s). WebIEEE 754 standard: binary32. The IEEE 754 standard specifies a binary32 as having: . Sign bit: 1 bit; Exponent width: 8 bits; Significand precision: 24 bits (23 explicitly stored); This gives from 6 to 9 significant decimal digits precision. If a decimal string with at most 6 significant digits is converted to the IEEE 754 single-precision format, giving a normal …
