     9    ECMA Section:       15.8.2.6  Math.ceil(x)

    10    Description:        return the smallest number value that is not less than the

    11    argument and is equal to a mathematical integer.  if the

    12    number is already an integer, return the number itself.

    13    special cases:

    14    - if x is NaN       return NaN

    15    - if x = +0         return +0

    16    - if x = 0          return -0

    17    - if x = Infinity   return Infinity

    18    - if x = -Infinity  return -Infinity

    19    - if ( -1 < x < 0 ) return -0

    20    also:

    21    -   the value of Math.ceil(x) == -Math.ceil(-x)
