  fn · Std.Column
• Std.Column.createF64Int -> Std.Column.ColumnF64

  Allocates an empty 64-bit float column with preallocated capacity.

  fn · Std.Column
• Std.Column.filterGtF64&Std.Column.ColumnF64 -> Float64 -> Std.Buffer.Buffer

  Evaluates the predicate (value > threshold) on valid float rows, producing a packed selection bitmap buffer.

  fn · Std.Column
• Std.Column.filterLtF64&Std.Column.ColumnF64 -> Float64 -> Std.Buffer.Buffer

  Evaluates the predicate (value < threshold) on valid float rows, producing a packed selection bitmap buffer.

  fn · Std.Column
• Std.Column.gatherF64&Std.Column.ColumnF64 -> &Std.Buffer.Buffer -> Std.Column.ColumnF64

  Gathers float row elements according to a permutation index buffer into a new contiguous unboxed column.

  fn · Std.Column
• Std.Column.getF64&Std.Column.ColumnF64 -> Int -> Option[Float64]

  Retrieves the float scalar at row, returning None if the row is null or out of bounds.

  fn · Std.Column
• Std.Column.isNullF64&Std.Column.ColumnF64 -> Int -> Bool

  Checks whether the float row at row is null or out of bounds.

  fn · Std.Column
• Std.Column.lengthF64&Std.Column.ColumnF64 -> Int

  Returns the number of rows stored in the float column.

  fn · Std.Column
• Std.Column.maxF64&Std.Column.ColumnF64 -> Option[Float64]

  Computes the maximum value among valid non-null elements in the float column.
