The Math object is not a function object. It does not have a [[Construct]]

internal method; it is not possible to use the Math object as a constructor
|

|
with the new operator. The Math object also does not have a [[Call]] internal
|
||||||
|
method; it is not possible to invoke the Math object as a function.
