Static image file format for uncompressed HDR (High Dynamic Range) images

Look for static image file formats that can store HDR (High Dynamic Range) images uncompressed.

I think HEIF and JPEG-HDR can store HDR, but I think these are irreversible compression files.
I think there is a format in which HDR can be stored uncompressed in image processing software, but is there such a file format?

If you have any information, please let me know.

PNG can handle 48bit color (16bit each RGB).
It is compressed by zlib, but it is reversible, and you can choose uncompressed if necessary.

OpenEXR also offers non-compression, reversible compression, and irreversible compression, handling fp16/fp32/uint32.
