Hi, I want to convert a floating number into a string and tried using sprintf() but as an older post from 2017 already noted, this function seems not to work with the Bluetooth stack:
base class, which specifies the set of operations to be implemented. */class target_float_ops { public: virtual std::string to_string (const gdb_byte *addr, const struct type *type, const char *format) const = 0; virtual bool from_string (gdb_byte *addr, const struct type *type, ...
In order to replicate this work, I need exactly one simple feature: a way to add an unquoted string as an BasicJsonValue: json j; j['accurate_value'] = json::unquoted_string("12.3456789); j['rounded_to_a_millimeter'] = json::unquoted_string("12.3"); j['rounded_to_a_millimeter']...
