The following query:

INSERT INTO skill (`emp_number`, `skill_id`, `year_exp`, `comments`)
VALUES ('4', '3', '23.45', '')

It is producing the error :

1 row inserted.
Warning: #1264 Out of range value for column 'year_exp' at row 1
year_exp column is of datatype decimal(2,2)

Please help me to pint out the error.
