+    File Name:          15.8-1.js
+    ECMA Section:       15.8 The Math Object
+
+    Description:
+
+    The Math object is merely a single object that has some named properties,
+    some of which are functions.
+
+    The value of the internal [[Prototype]] property of the Math object is the
+    Object prototype object (15.2.3.1).
+
+    The Math object does not have a [[Construct]] property; it is not possible
+    to use the Math object as a constructor with the new operator.
+
+    The Math object does not have a [[Call]] property; it is not possible to
+    invoke the Math object as a function.
+
+    Recall that, in this specification, the phrase "the number value for x" has
+    a technical meaning defined in section 8.5.

+                        close to the argument. then the result is the number value
+                        that is closer to Infinity.  if the argument is an integer,
+                        return the argument.
+                        special cases:
+                            - if x is NaN       return NaN
+                            - if x = +0         return +0

+                            - if -0.5 <= x < 0  return -0
+                        example:
+                            Math.round( 3.5 ) == 4

+    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)
