[postgis-users] Decoding canonical text of geometry(POINT) data

I have a database table with a `geometry(POINT, 4326)` column.

I need to decode its canonical text representation in the form of


into its components 82.9919732, 55.0274045 *without* calling PostGIS
functions like `st_x` and `st_y` (this is a limitation of the codebase
I'm working with — canonical text is all I have).
Could someone point me to any docs about the encoding details so
that I could reimplement it?
