Applying successive shaders to a texture while keeping float precesion

Question

I have a render texture in Unity and am applying successive shaders to it as following:

     Graphics.Blit(Tex1, Tex2, myMaterialA);
     Graphics.Blit(Tex2, Tex3, myMaterialB);
     Graphics.Blit(Tex3, Tex4, myMaterialC);

In my shaders, I only work with floats, but the outputed color values get quantified on 8 bits since the output texture is RGBA 32 bits.

In my example, is there a way to keep float precisions for the intermediate results (Tex2, Tex3) and only convert the final texture Tex4 to RGB 32bits ?

You should refrain from asking multiple questions within a Question, it tends to get your Question closed as "too broad." — Draco18s no longer trusts SE, Jun 07 '18 at 17:32
@Draco18s Alright, I edited my post to make it more concise and kept only one question. — Mai Kar, Jun 08 '18 at 09:25

Both Texture2D and RenderTexture can have different format than ARGB32.
