To make it comply with TEP124. This allows for implementation that want to estimate bi-directional estimate just by exchanging beacons. > 2) The calculations of the inqualities and ETXs are done using unsigned int. > However, these calculations give float numbers. Why use integers then when > float numbers give more precise estimates? Float, as opposed to fixed-point representation, is not without its disadvantage. Code/CPU overhead of float operations on some platforms. With limited precision, it might be hard to compare two floats that are close to each other. - om_p _______________________________________________ Tinyos-help mailing list [email protected] https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
