Nico Williams scripsit:

> ECMAScript, Perl, Python, libjv, Jansson, json-c -- all have doubles.

My own implementation in Scheme will interpret a number with a decimal
point or an exponent as an IEEE double, except on the few Schemes
that don't support inexact numbers.  An integer will be interpreted
as an exact integer up to the system limit, which varies from 24-bit
to limited only by memory size.
