It would be great, if you could follow the naming convention -- even though it's not explicitly defined here -- 

Store - Storage class
FLV - Works only for Fixed Length Vector
F1_EQ_INT - Description of field with operator

So in you case this would become

`STORE_FLV_F1_BTW_FLOAT`

and 

`STORE_FLV_F1_BTW_INT`
