binary to decimal when binary with radix point

I have to convert the following binary number to decimal: 11000101.101

I am using

bin2dec('binary number')

but is does not work with a radix point

Answer 1

This is easy to do yourself:

>> str = '11000101.101';
>> idx = str~='.';
>> vec = 1:sum(idx);
>> pwr = sum(str(idx)==str(vec)) - vec;
>> sum((str(idx)-'0') .* 2.^pwr)
ans =
               197.625

Answer 2

[Walter Roberson]

parts = strsplit(str, '.') ;
dec2bin(parts{1}) + dec2bin(parts{2})/2^length(parts{2})

[Harel Harel Shattenstein]

I should use a command as + does not seems to be defined for those variables (parts{1} and parts{2} are strings)

[Stephen23]

@Harel Harel Shattenstein: there is a mistake in this untested code, the function dec2bin should actually be bin2dec. Otherwise it is correct.

[Walter Roberson]

parts = strsplit(str, '.') ;
bin2dec(parts{1}) + bin2dec(parts{2})/2^length(parts{2})

That's what I get for posting at 3 in the morning ;-)
