Is it possible to use BITAND operator in BigQuery with Non Integer values?

I am using BITAND (&) operator in BigQuery

select (cast val as INT64) & pow(2,63) = pow(2,63)

The value for the field Val and pow(2,63) is exceeding the maximum value of integer and hence BITAND is not working.

I typecasted it to other data types but they are not working with BITAND operator

Any suggestions?

Try splitting and processing, casting both values to int64. Also, note that Bitwise and operator throws an error if X and Y are bytes of different lengths.

WITH CTE AS (
  SELECT
    CAST(val AS INT64) AS val,
    CAST(POW(2, 63) AS INT64) AS bitmask
  FROM
    WhateverTable)
SELECT
  val,
  bitmask,
  IF(val & bitmask = bitmask, TRUE, FALSE) AS result
FROM
  CTE;
