[Gnash-commit] [patch #8942] Patches to improve number value handling in ExternalInterface

[Nutchanon Wetchasit]

Follow-up Comment #1, patch #8942 (project gnash):

Current libgnashplugin marshall `double` value sent from NPRuntime
to `<number>` data using default iostream with no specific precision
<https://savannah.gnu.org/bugs/?47280#comment4>
specified. This causes precision loss as not enough decimal digits
were used to represent the value.

Patch 2 of 2:
See the attached
`0002_plugin-externalinterface-number-marshall-enough-digits.patch`.

This patch explicitly specifies iostream floating point precision to
`std::numeric_limits<double>::max_digits10` (C++ 11) which is
enough significands to accurately reproduce the original `double` value
(provided that receiver end's parser library implements the correct
rounding).

This partially fixes bug #47280.
