Absolute humidity measurement about bme280 HOT 4 CLOSED

IMHO that is not a functionality of this sensor so it should not be part of the library either. There are thoughts about another library, maybe this code snippets helps you
`#include <math.h>

double calculationAbsHum(float t, float h)
{
double temp;
temp = pow(2.718281828, (17.67 * t) / (t + 243.5));
return (6.112 * temp * h * 2.1674) / (273.15 + t);
}
String(calculationAbsHum(temperature, humidity)) + " g/m3");`

Thanks, is there any scientific reference on the Internet where this approximation is listed ?
