+    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)
