how to change this value in number??????

X=1.0202e+05 - 6.1123e+11i

Answer 1

>> format long g
>> X=1.0202e+05 - 6.1123e+11i
X =
     102020-611230000000i

Here i denotes complex, which is a number

The display number depends on how you set the format (you can change the default setting)

Example:

     >> format long

or

     >> format short

For detail please see the Matlab documentation.

To avoid i (Complex Number Notation), you have to deal with individually

• real(X)- Gives Real Part
• imag(X) Gives Imaginary Part

Example:

>> real(X)
ans =
      102020
>> imag(X)
ans =
      -611230000000

Hope it helps!

Thank you very much Sir

@Prakash always welcome?

[Prakash Choudhary]

and if i ask you one more thing how can i miltiple this number with any number for example X=1.0202e+05 - 6.1123e+11i

Y=X.*2

is that right ?

[KALYAN ACHARJYA]

X*2 (As dot not needed, which use in vector multiplication, if X is vector then only)

[Prakash Choudhary]

so we only use the real number here for multiplication??

[KALYAN ACHARJYA]

No, please read Multiplying a complex number by a real number, it multiply both real and imag part.

X=1.0202e+05 - 6.1123e+11i >> Complex number

Y=X*2, here 2 is real number
