Hi all,

IEEE 754 double cannot express exact float values. That said,
float values expressed by json/serialize/var_export/echo/print
are not precise enough in many cases.
Issues:
- json_encode() uses EG(precision)=14 that truncates float values.
echo()/print()
does this as well.
- large EG(precision)/PG(serialize_precision) prints meaningless values.
This RFC proposes zend_dtoa()'s 0 mode support which rounds float value
to nearest value.

This change is simple enough for PHP 7.0. IMO.
Comments/suggestions are appreciated!
It's been 2 weeks and no comment for this.
I'll start voting.
Cool, but there's no voting available...? :-)
Thanks.
