[Tinyos-help] adjustLQI function

[funofnet Funofnet]

Hi,
Please,
What is the meaning of this function:
 
uint16_t adjustLQI(uint8_t val) {
    uint16_t result = (80 - (val - 50));
    result = (((result * result) >> 3) * result) >> 3;  ( simply [(result)^3]/64 )
    return result;
  }
Thanks in advance.
Funofnet
