Exponential notation
Cassandra supports exponential notation.
CREATE TABLE test(
id varchar PRIMARY KEY,
value_double double,
value_float float
);
INSERT INTO test (id, value_float, value_double)
VALUES ('test1', -2.6034345E+38, -2.6034345E+38);
SELECT * FROM test;
id | value_double | value_float
-------+--------------+-------------
test1 | -2.6034e+38 | -2.6034e+38
