Unable to fetch more decimal points for values stored in sldd

I have a variable (name : dummyVar) in sldd with value 132.99525

When i fetch this variable from sldd using matlab code and checked the value.

The value fetched using matlab code was 132.9952.

Not all decimal points fetched here. I would like to understand the reason behind this behaviour !!

You need to learn about the format command. All of the digits are still there, they were just not reported. I'll add a few digits.

x = 132.9952512345

x = 132.9953

The default for format is short.

help format

 format - Set output display format
    This MATLAB function changes the output display format to the format
    specified by style.

    Syntax
      format(style)

      fmt = format
      fmt = format(style)

    Input Arguments
      style - Format to apply
        character vector | string scalar | DisplayFormatOptions object

    Output Arguments
      fmt - Current display format
        DisplayFormatOptions object

    Examples
      openExample('matlab/ChangeCurrentFormatExample')
      openExample('matlab/DisplayValuesinDefaultandHexadecimalFormatExample')
      openExample('matlab/DifferenceBetweenShortandLongEngineeringNotationExample')

    See also DisplayFormatOptions, disp, fprintf, formattedDisplayText

    Introduced in MATLAB before R2006a
    Documentation for format
       doc format

F = format

F = 
  DisplayFormatOptions with properties:

    NumericFormat: "short"
      LineSpacing: "loose"

However, you want to see more digits. long g is generally a good choice.

format long g
x

x = 
            132.9952512345

If you want even more control, you can always use tools like sprintf.

Don't confuse display with value...try

format longg
dummyVar
format short
dummyVar

"format short" is the default setting; you can change that in the user preferences or dynamically at will...

See format for all the choices available.
