Oracle: Convert string to double

Viewed 19281

This is my query for a database pull:

SELECT DISTINCT
TEMPLATE_GROUP_PROPERTIES.PROPERTYTYPE,
PROPERTY.PROPERTYVAL

FROM
TEMPLATE_GROUP_PROPERTIES

LEFT OUTER JOIN PROPERTY_DATA
ON (TEMPLATE_GROUP_PROPERTIES.PROPERTYGROUPID = PROPERTYDATA.PROPERTYGROUPID)

WHERE
PROPERTY.PROPERTYVAL = :propValue

Whoever created the database made the Property.Propertyval column a column defined as a string when it is represented as scientific notation numbers (4.0E-3, 2.0E2, etc). I need to convert either the string to a double or the double to a string whatever way would work and I don't know how. I have tried messing around with the TO_NUMBER() function and have found nothing of help so far.
