SQL - How do I get only the numbers after the decimal?

Question

How do I get only the numbers after the decimal?

Example: 2.938 = 938

Answer 1

You can use FLOOR:

select x, ABS(x) - FLOOR(ABS(x))
from (
    select 2.938 as x
) a

Output:

x                                       
-------- ----------
2.938    0.938

Or you can use SUBSTRING:

select x, SUBSTRING(cast(x as varchar(max)), charindex(cast(x as varchar(max)), '.') + 3, len(cast(x as varchar(max))))
from (
    select 2.938 as x
) a
