9 ECMA Section: 15.8.2.9 Math.floor(x)
10 Description: return the greatest number value that is not greater
11 than the argument and is equal to a mathematical integer.
12 if the number is already an integer, return the number
13 itself. special cases:
14 - if x is NaN return NaN
15 - if x = +0 return +0
16 - if x = -0 return -0
17 - if x = Infinity return Infinity
18 - if x = -Infinity return -Infinity
19 - if ( -1 < x < 0 ) return -0
20 also:
21 - the value of Math.floor(x) == -Math.ceil(-x)
