1.11 + File Name: 15.8.2.9.js
1.12 + ECMA Section: 15.8.2.9 Math.floor(x)
1.13 + Description: return the greatest number value that is not greater
1.14 + than the argument and is equal to a mathematical integer.
1.15 + if the number is already an integer, return the number
1.16 + itself. special cases:
1.17 + - if x is NaN return NaN
1.18 + - if x = +0 return +0
1.19 + - if x = -0 return -0
1.20 + - if x = Infinity return Infinity
1.21 + - if x = -Infinity return -Infinity
1.22 + - if ( -1 < x < 0 ) return -0
1.23 + also:
1.24 + - the value of Math.floor(x) == -Math.ceil(-x)
