Decimal metafield using MetaFieldBuilder

Hi,

I'm trying to add a metafield to the cls_organization table, by using the MetaFieldBuilder. Now, creating most of the fields works fine, however, I am not able to create a decimal with a specific precision and scale. When I use the CreateDecimal method, a float is created, which is not what I want.

If I add en entry in the [mcmd_MetaFieldType], with name "Decimal" and MCDataType 18, and use the CreateMetaField method instead where I specify "Decimal" as the typeName and pass an AttributeCollection with specific Precision and Scale, it works fine.

What I am wondering is, is this a safe way to achieve the decimal column in the database?

Best regards
