MATLAB: How to convert number to real number

convert numbermsereal number

Dear all,

My code calculates the MSE as a result

perf =
    1.1970e-011

How I convert this type of number to real or some "normal" number?

Thank you for your answers.

This is a real number. Just small enough that scientific notation was employed to display it, to avoid a plethora of zeros. There is NOTHING abnormal about it.

1.1970e-011 == 1.1970 * 10^(-11)

For the second time recently, I find myself amazed that kids no longer learn what scientific notation is in school anymore.

MATLAB: How to extract the first part of a number in standard form/scientific notation

One of many ways to do this is to:

1. Convert the number into a scientific notation string

2. Split the string using 'e' as the delimiter

3. Convert the first element of the resulting array from the split to a double.

x = 346346346^2; % Create some big number
string = sprintf('%.2e', x); % Convert number to a scientific notation string with 2 decimal places of precision
stringParts = strsplit(string,'e'); % Split the string where 'e' is
firstPart = str2double(stringParts(1)); % Get the 1st part of stringParts which is the first part of standard form.

The value is too big to show "real number"

>> a=1000
a =
        1000
>> format ShortEng
>> a
a =
     1.0000e+003
