Convert binary to decimal is not correct.

Hi everyone,

I have the following code

value=[bitget(binary_data(1),4:-1:1),...
              bitget(binary_data(2),8:-1:1),...
              bitget(binary_data(3),8:-1:1),...
              bitget(binary_data(4),8:-1:1)]             
value=bi2de(value,2,'left-msb')

The output is not according to what used to be. Any hints what might be the problem?

value =

    Columns 1 through 25

      0    1    1    0    0    0    1    1    1    0    0    0    1    1    0    1    0    1    0    1    1    1    0    0    0

    Columns 26 through 28

      0    0    1

value =

    255

Thank you

What is binary_data, and what values does it have/return ?

value = bi2de(double(value),2,'left-msb')

You were working with uint8, so the arithmetic was being done in uint8, which "saturates" at 255.
