Summary0003964: Oracle's REAL datatype should map to DOUBLE in MariaDB, not FLOAT
DescriptionCurrently, REAL is mapped to a FLOAT in MariaDB. Should be mapped to a DOUBLE.

Interestingly, the XML passes FLOAT over as a FLOAT(63) from Oracle, which is accurate (FLOAT has a binary precision of 63 on Oracle)

create table test26 (myreal real,
     myId varchar(256), primary key (myId));

Results in the following Create Table on MariaDB side:

[store-001] - DefaultDatabaseWriter - About to create table using the following definition: <?xml version="1.0"?>
<!DOCTYPE database SYSTEM "">
<database name="dataextractor">
    <table name="TEST26">
        <column name="MYID" primaryKey="true" required="true" type="VARCHAR" size="256">
            <platform-column name="oracle" type="VARCHAR2" size="256"/>
        <column name="MYREAL" type="REAL" size="63">
            <platform-column name="oracle" type="FLOAT" size="63"/>
