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.
29 - if x is NaN return NaN
32 - if x = Infinity return Infinity
33 - if x = -Infinity return -Infinity
34 - if ( -1 < x < 0 ) return -0
36 - the value of Math.ceil(x) == -Math.ceil(-x)
