Looks like some rounding errors:

  gridPoint
    ✓ should return center point of pointy-topped hexagonal grid system
    1) should return center point of flat-topped hexagonal grid system

  gridPoints
    ✓ should return sequential gridPoints (pointy-topped)
    ✓ should return sequential gridPoints (flat-topped)


  3 passing (42ms)
  1 failing

  1) gridPoint should return center point of flat-topped hexagonal grid system:

Sorry, this is a problem about environmentally dependent floating-point calculation maybe so difficult to resolve it.
