Example: Querying SELECT FLOOR (136E-1);

The following query returns the FLOAT value 13E0, since 13 is the largest integer that is less than the FLOAT value 13.6E0.

   SELECT FLOOR (136E-1);

Example: Querying SELECT FLOOR(-6.5);

The following query returns a DECIMAL value of -7.0 since -7 is the largest integer that is less than the DECIMAL literal -6.5.

   SELECT FLOOR(-6.5);

Example: Querying SELECT FLOOR (CAST(-6.5 AS DECIMAL(2,1)));

The following query returns a value of -7.0 with a data type of DECIMAL(3,1), since -7 is the largest integer less than DECIMAL -6.5. Note that the precision of the return value is increased by 1.

   SELECT FLOOR (CAST(-6.5 AS DECIMAL(2,1)));
