> [IS_NAN|https://cloud.google.com/bigquery/docs/reference/standard-sql/mathematical_functions#is_nan]
> functions. The first returns whether the specified value is infinite, the
> second returns whether the specified value is `NaN`.
> Example 1: `SELECT IS_INF(3)` would return `FALSE`.
> Example 2: `SELECT IS_INF(CAST('Infinity` AS DOUBLE))` would return `TRUE`.
