What does "real" in shaders of lightweight pipeline means? It seems some sort of number.

    I found there is some shader functions use real as return type, it seems some sort of number. What does it exactly means, and what's the difference between it and others(float, half, fixed).

    Hi!

    Real is either float or half, depending on the platform. You can check the file Common.hlsl.
