40 ECMA Section: 15.8.2.6 Math.ceil(x)
41 Description: return the smallest number value that is not less than the
42 argument and is equal to a mathematical integer. if the
43 number is already an integer, return the number itself.
45 - if x is NaN return NaN
48 - if x = Infinity return Infinity
49 - if x = -Infinity return -Infinity
50 - if ( -1 < x < 0 ) return -0
52 - the value of Math.ceil(x) == -Math.ceil(-x)
