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)
