- File Name: 15.8.2.9.js
- ECMA Section: 15.8.2.9 Math.floor(x)
- Description: return the greatest number value that is not greater
- 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.floor(x) == -Math.ceil(-x)
