Indeed.

But I think it's helpful to distinguish between a language and its
implementation.  For example, the CDC 6600 supported FORTRAN 66 with its
distinction between integer and real types.  The integer types where
implemented using floating point but they behaved as specified by the
language specification.  Likewise, an ECMAScript implementation is
permitted to use integer hardware in various ways, provided the results
conform with all the details of the language specification.
