 Reporter:  komzpa   |      Owner:  komzpa
     Type:  patch    |     Status:  assigned
 Priority:  medium   |  Milestone:  PostGIS 2.5.0
Component:  postgis  |    Version:  trunk
 Keywords:           |
---------------------+---------------------------
 We've got discrepancies on:
  - what is precision parameter (number of signicant digits or number of
 digits after comma);
  - +/-0 blinks in tests on -Ofast;
  - what's the size of buffer to allocate for text representation of
 coordinate.

 Patch that syncs it:
