sscanf is truncating my floating point number

Hi

I am trying to use sscanf to extract data from a string, but it is truncating my floating point number. The code I am using is:

sscanf(tempstr, '%f V,%d counts,%d ms')

The data is like this: 0.2981427192 V,34 counts,500 ms

I get: ans =

    0.2981
   34.0000
  500.0000

I want all the floating point digits. I have tried to specify a length (%12f), and numerous other things, none of which have worked. Any help would be appreciated.

Thanks Rebecca

@Rebecca Prescott: Don't worry, MATLAB has not eaten your digits! Actually sscanf is working fine: it is just how the values are displayed. See format for more info on different display options.

Type:

format long g

in your script or Command Window before your sscanf call. All the digits should be visible.

Thank you so much, that worked.
