Converting to scientific notation in matlab

Hi Team,

Could anyone let me know how I can represent the below number

5000000

as 5*(10^6) or 5e^6

in matlab?

The reason is that everytime I have to count the number of zeros, I was wondering if there was an easier way.

We are not a "team". We are just a number of people who act as complete volunteers, individually.

You cannot "represent" it that way. A number is just a number. In fact, it is stored in a binary form internally. So you cannot tell MATLAB to store it in some other form, perhaps as scientitfic notation.

You CAN make a copy of the number, stored in a variable as a text string. For example,

A = 500000

A = 500000

Now create a string version of the number.

B = sprintf('%10.f',A)

B = '    500000'

So B is now a character string. Or you could have done this:

C = num2str(A)

C = '500000'

Or, if you want an explicitly scientific notation form...

D = sprintf('%10e',A)

D = '5.000000e+05'

Honestly, I don't think any of these ways are any easier to deal with for whatever are your purposes. But whatever floats your boat.

Thank you so much !

this is exactly what I was looking for, although I understand its a string.
