relaxed_precision during Build Texture - what is it? Can it be disabled?

[jenkinsm]

I am trying to automate the process of replacing images in a folder to make different texture maps, and I am using EXR input images with HDR ranges. I noticed in the console output "relaxed_precision=on" which worries me because i need full precision for my textures.

I don't see any reference to it in the API PDF, nor can I find anything about it from searching.

Does anyone know what this does, or if it can be set to 'off'?

This is where I'm seeing it:

2025-03-05 15:56:39 BuildTexture: blending-mode = Mosai cBlending,
texture_size = 16384, encode_winner_camera_id = off, fill_holes = off,
ghosting_filter = on, texture_type = Diffuse map, enable_gpu = on,
relaxed_precision = on
