Gray code is used for rotary encoders. Bin2gray() works with byte , integer, word and long variables.

The data type of the variable that will be assigned determines if a byte, word or long conversion will be done.

Depending on the data type of the target variable the following routine will be called from mcs.lbx:

_grey2Bin for bytes , _grey2bin2 for integer/word and _grey2bin4 for longs.
