Description

He encontrado un error horrible en RapidJSON::CppTools::Set2JSON cuando le pasas un número mayor de 231 sin decimales, o con decimales nulos, que lo convierte por todo el morro en -231 = -2147483648

Set data = [[
413116249059.285,
416010796541.989,
417927630208.313,
414052000000,
420976000000.0,
422588000000.000,
422588000000.0001,
422588000000.00000000000000000001
]];
Text json = RapidJSON::CppTools::Set2JSON(data);

Este es el absurdo resultado

"[413116249059.285,416010796541.989,417927630208.313,-2147483648,-2147483648,-2147483648,422588000000.0001,-2147483648]"

Estos números aparecen en las series macroeconómicas con cierta frecuencia y en concreto en la que necesito para el modelo de pruebas.
