--------------------------------------
Summary: Support fixed precision data type
Key: CASSANDRA-9550
URL: https://issues.apache.org/jira/browse/CASSANDRA-9550
Project: Cassandra
Issue Type: Improvement
Reporter: Brian Hess
SQL databases support a fixed precision data type. When converting data models
from SQL DBs to Cassandra, the choices are not clear. DOUBLE or FLOAT are
possibilities, but with UDFs and Aggregates this is actually a lot less clear,
as you really do need fixed precision arithmetic. That is, one flaw with
floating-point math is that the order of the operations can change the final
result. That is not an issue with fixed precision arithmetic (though other
trade-offs are there).
