BUG : FORMS not displaying values stored in FLOAT datatypes.

Question

APEX 2.2.1.
Error occurs on both V9.2.0.4 and V10.2.
I'm working on a "report with form" combination and have been fighting a problem where the data entered into a form will save correctly and show in the report, but when you choose to edit the record to update it, the value will not display in the form at all.
I went round and round, and finally discovered that the problem had to do with the FLOAT datatype being used to store the data.
When creating a default "Report with Edit form" on the following two example tables, the form works correctly with SLA_SCHEDULE2 but not with SLA_SCHEDULE1
CREATE TABLE SLA_SCHEDULE1
ID NUMBER NOT NULL,
NAME VARCHAR2(128 BYTE) NOT NULL,
TRACING_PERCENTAGE FLOAT(126),
RUNS_PER_PERIOD NUMBER,
SECONDS_PER_PERIOD NUMBER,
SCHEDULE_TYPE VARCHAR2(16 BYTE) NOT NULL
CREATE TABLE SLA_SCHEDULE2
ID NUMBER NOT NULL,
NAME VARCHAR2(128 BYTE) NOT NULL,
TRACING_PERCENTAGE NUMBER,
RUNS_PER_PERIOD NUMBER,
SECONDS_PER_PERIOD NUMBER,
SCHEDULE_TYPE VARCHAR2(16 BYTE) NOT NULL
The only workaround I have so far is to change the datatype of the column.

Based on the advice Scott gave above, I've created this function...
CREATE OR REPLACE FUNCTION Get_Float_Value
p_table_name           VARCHAR2,
     p_float_column_name     VARCHAR2,
     p_key_id_name          VARCHAR2,
     p_key_id_value           VARCHAR2
RETURN FLOAT IS
TYPE FLOAT_CURSOR IS REF CURSOR;
f_cur FLOAT_CURSOR;
FLOAT_VALUE FLOAT(126);
SQL_STMT VARCHAR2(500);
BEGIN
     SQL_STMT := 'select :a from :b where :c = :d';
     SQL_STMT := REPLACE(SQL_STMT, ':a', p_float_column_name);
     SQL_STMT := REPLACE(SQL_STMT, ':b', p_table_name);
     SQL_STMT := REPLACE(SQL_STMT, ':c', p_key_id_name);
     SQL_STMT := REPLACE(SQL_STMT, ':d', p_key_id_value);
OPEN f_cur FOR SQL_STMT;
     LOOP
     FETCH f_cur INTO FLOAT_VALUE;
     EXIT WHEN f_CUR%NOTFOUND;
     RETURN FLOAT_VALUE;
     END LOOP;
     RETURN NULL;
END Get_Float_Value;
This allows you to call the function ANYWHERE you use a FLOAT, without having to create one function per table/column you might need to use it against.
I know that I could have used a 'USING' statement on the cursor to do the replacements, but I always find it easier to debug replacement values using the REPLACE function.
