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