   File Name:          15.8.2.6.js
   ECMA Section:       15.8.2.6  Math.ceil(x)
   Description:        return the smallest number value that is not less than the
   argument and is equal to a mathematical integer.  if the
   number is already an integer, return the number itself.
   special cases:
   - if x is NaN       return NaN
   - if x = +0         return +0
   - if x = 0          return -0
   - if x = Infinity   return Infinity
   - if x = -Infinity  return -Infinity
   - if ( -1 < x < 0 ) return -0
   also:
   -   the value of Math.ceil(x) == -Math.ceil(-x)
