Convert a string to number

Hi, I want to convert a string into a number however I don't want to use str2num since I loose extra digits (see example below). Can I use some other MATLAB function?

data = 0.0782238;
s = str2num(data); %Don't want this since s = 0.0782 and I'm loosing three extra digits

Are you sure? It could just be matlabs display. Try

 format long

ok, so MATLAB will store the value but shortens the display? ;)

[Patrik Ek]

Exactly. You could try

a=1.1111111;
a
b=2.2222222;
format long;
a+b

nice, thx :)

str2num() does not lose those extra digits. Instead, you are not displaying the full width of the number. At the MATLAB command line give the command

   format long g

and try your code again.

how about just using format long

data = '0.0782238';
data = str2num(data);
format long
data
