Hi all!
I've this bytes "buffer" example: {0x20,0x20,0x20,0x20,0x34,0x35,0x36,0x31,0x34} which represent 0 0 0 0 4 5 6 1 4 or (4561.4). How to convert it into hex or dec. value and try to calculate percent of other value?
Thanks. |

Put a 0x00 on the end to make it into a string. Then use atof() to convert
the string to a float. Then divide the float by 10 to get the final number. |
