            Bug ID: 200636
           Summary: [WHLSL] fmod in the standard library is broken on
                    negative inputs
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebGPU
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: rmorisset at apple.com

e.g. fmod(-42.0, -3.0) should return -1.0, not 1.0.
I don't think it should return 0.0 for fmod(42, -3) or fmod(-42, 3) either.
I suspect it could just return the fmod of Metal, but I am still investigating.
