michael@0:    Description:        return the smallest number value that is not less than the
michael@0:    argument and is equal to a mathematical integer.  if the
michael@0:    number is already an integer, return the number itself.
michael@0:    special cases:
michael@0:    - if x is NaN       return NaN
michael@0:    - if x = +0         return +0
michael@0:    - if x = 0          return -0
michael@0:    - if x = Infinity   return Infinity
michael@0:    - if x = -Infinity  return -Infinity
michael@0:    - if ( -1 < x < 0 ) return -0
michael@0:    also:
michael@0:    -   the value of Math.ceil(x) == -Math.ceil(-x)
