Context

Uint16 values from 65520 through 65535 round to infinity in a half-float texture. Finite floating-point inputs can also overflow. A non-finite texel can affect interpolation with its neighbors. Half-float conversion

Results

With half-float storage, 65535 uploads as 65504. A partial update containing -70000 and 70000 stores -65504 and 65504 respectively.

Changes

Clamp finite values to the representable range in the half-float conversion shared by full and partial WebGPU texture uploads.
