how to round the binary bit into 8 bit

for example:

4 = binary is 100 into 00000100

1=binary is 1 into 00000001 any matlab code...

result is 8 bit binary

Not sure what the real question is, but dec2bin has an option for minimum number of digits. E.g.,

>> dec2bin(1,8)
ans =
00000001
>> dec2bin(4,8)
ans =
00000100

The result is of course char strings. If you want or need something else you will need to provide us with more details.

Hi AR

The best you have to do is to use fi objects. I recommend to have a look on matlab help site on this topic.

By the way, I'm giving an example

x=4;
X=fi(x,0,8,0);  % x:value, 0:signed or not, 8:bits, 0:fractional part
X.data
X.bin
