Countrows returns null instead of 0

[Anonymous]

I have a data like this 

Column 1	Column 2
null	6
null	3
null	null

I am counting the occurrences of values greater than 9 in both columns but both columns returns null while in reality the column 1 should return null while the column two should return 0. 

var column1 = COUNTROWS ( FILTER ( 'nps', 'nps'[Column 1] IN { 7, 8, 9, 10 } ) )

var column2 = COUNTROWS ( FILTER ( 'nps', 'nps'[Column 2] IN { 7, 8, 9, 10 } ) )

I am doing some other calculation at the end as well

Is there any way we can ignore the null values in the columns from calculations so that with the rows that have a data with values but returns a null I can force zero it?

COUNTROWS of an empty table is BLANK not 0

To force zero use

var column2 = COUNTROWS ( FILTER ( 'nps', 'nps'[Column 2] IN { 7, 8, 9, 10 } ) ) + 0

Genius!

Won't that automatically use 0 where the column or cell value is actually null and should remain the same?

FILTER ( 'nps', 'nps'[Column 2] IN { 7, 8, 9, 10 } ) returns an empty table. Any aggregation of an empty table in DAX returns a blank not 0
