Warning: floating constant exceeds range of ‘double’
NOTE: this is only applicable for ArduinoJson strictly older to 5.11.1
This may happen if you’re targeting a platform where double
s have only 32-bits.
Usually ArduinoJson can detect this, but when it doesn’t you may have the following errors:
warning: floating constant exceeds range of 'double' [-Woverflow]
warning: floating constant truncated to zero [-Woverflow]
or
Error[Pe030]: floating constant is out of range
The solution is to define ARDUINOJSON_DOUBLE_IS_64BITS
to 0
:
#define ARDUINOJSON_DOUBLE_IS_64BITS 0
#include <ArduinoJson.h>
