           Summary: Make std.math.isIdentical work in CTFE
           Product: D
           Version: D2
          Hardware: All
                OS: All

          Severity: enhancement
          Priority: P1

Making std.math.isIdentical work for real NaN when real is more than 64 bits requires either changing `is` for floats to be a binary comparison (like https://github.com/dlang/dmd/pull/7568) or adding support for CTFE reinterpretation of reals as byte arrays. This is a subissue of Issue #17007.
