JSON Object floating 연산 오류 해결

/**
 * Put a key/double pair in the JSONObject.
 *
 * @param key   A key string.
 * @param value A float which is the value.
 * @return this.
 * @throws JSONException If the key is null or if the number is invalid.
 */
public JSONObject put(String key, float value) throws JSONException {
    this.put(key, Double.parseDouble(String.valueOf(value)));
    return this;
}

putting float values into a JSONObject is using the put(String, double) method.
Unfortunately, this type of cast causes floating point precision problems.
For example, the float number 6.99 is translated to the double 6.989999771118164
