Mongo DB C ++格式错误的十进制格式，请在末尾添加“ .0”，并将其转换为JSON

Question

When I add decimal numbers (float or double) on mongo object and after convert to JSON, the converter change "." by "," add ".0" to end of each number.

float x = 2.3;
float y = 2.0;

mongo::BSONObj obj = BSON("x" << x << "y" << y);

std::string json = obj.toString();

// {"x":2,3.0, "y": 2,0.0}

Answer 1

Ok. I should use "jsonString()" instead of "toString()"

float x = 2.3;
float y = 2.0;

mongo::BSONObj obj = BSON("x" << x << "y" << y);

std::string json = obj.jsonString();
