## `BINARY_QUANTIZE`

**Applies to:** ✅ Data 360 SQL ✅ Tableau Hyper API

Encodes each array element into a single bit, compressing the vector by approximately 32x.

*   `<array>`: The vector to quantize (`array(real)` or `array(double-precision)`).

Returns a bytea value where each bit represents whether the corresponding array element is greater than 0 (1) or not (0).

*   Elements greater than 0 are encoded as 1, all others (including 0 and negative values) as 0.
*   The compression ratio is approximately 32x.

Convert a numeric vector to binary representation.

Returns `'0011'`, where negative values become 0 and positive values become 1.

*   [Array Data Type](https://developer.salesforce.com/docs/data/data-cloud-query-guide/references/dc-sql-reference/array.html)
