Summary: NPAPI: No way of telling the difference between 'ints'
and 'doubles'.
Product: WebKit
Version: 526+ (Nightly build)
Platform: Macintosh
OS/Version: Mac OS X 10.5
Status: UNCONFIRMED
Severity: Normal
Priority: P2
Component: Plug-ins
AssignedTo: webkit-unassigned at lists.webkit.org
ReportedBy: playmobil at google.com
Javascript technically only has a double datatype, however there is utility in
telling the difference between the following two calls from JS into an NPAPI
plugin:
plugin.method(42);
plugin.method(42.0);
In Mozilla, the former yields a variant for which NPVARIANT_IS_INT32() returns
true, and for the latter NPVARIANT_IS_DOUBLE() returns true.
In WebKit there is no way to tell the difference (all numeric variants are
reported as doubles).
A sample use case is an NPAPI plugin which needs to stringify numeric values,
in this case there is no way of knowing whether a valid string representation
would be '42' or '42.0'.
This bug affects Google Gears.
