Use the percentile function, as per the product documentation:
Returns the exact pth percentile of a column in the group (does not work with floating point types). p must be between 0 and 1. NOTE: A true percentile can only be computed for integer values. Use
PERCENTILE_APPROXif your input is non-integral.
If you are not able to get 'expected result' then your going to add a lot more detail to your question, as in what is the data, your query, and the expected result.
