[Stlport-devel] num get float

[<fra...@fr...>]

Hi

    I am working on the code used by STLport to read floating point 
numbers from stream. I have already fix some problems with long double 
and I have some more fixes to perform but before committing them I would 
like to get an answer to a question. Does anyone know why in 
_Stl_string_to_double function max_digits is defined as 
numeric_limits<double>::digits10 + 2 ? Why this additional 2 ? I have 
already detected that the 34 value used in _Stl_string_to_long_double is 
too much, when 34 digits are stored there is an overflow when computing 
value in _Stl_atod. I simply would like to know if we have to keep this 
arbitrary 2 and if so add a comment explaining why.

Thanks
