You're correct, I was so focused on very low precision that I missed the first value 0.003921568859368563 multiplied by 255 gives 1.000000059138983565. However it still doesn't solve the question, and setting the value to 1/255 (1/256 would be incorrect) doesn't allow to set the color to 0x01…

Then you see: 1 (0.0039...) for the next 4 steps, 2 for the next 4 steps (0.0078...) and so on. If he is using the shader and it continues to work that way, you should see the value for 5 (0.0195...) in some of the other steps. If the values are really skipped like X Y indicates, that is a different issue. Based on Taiyo's test, all 256 values should be possible. | |
