  24     ECMA Section:       15.8.2.6  Math.ceil(x)
  25     Description:        return the smallest number value that is not less than the
  26                         argument and is equal to a mathematical integer.  if the
  27                         number is already an integer, return the number itself.
  28                         special cases:
  29                             - if x is NaN       return NaN
  30                             - if x = +0         return +0
  31                             - if x = 0          return -0
  32                             - if x = Infinity   return Infinity
  33                             - if x = -Infinity  return -Infinity
  34                             - if ( -1 < x < 0 ) return -0
  35                         also:
  36                             -   the value of Math.ceil(x) == -Math.ceil(-x)
