How to separate integers and decimal numbers from given values?

How to separate integers and decimal numbers from given values?

[Adam]

Can you give an example. I don't understand what you are asking.

Answer 1

>> V = [1,2.3,4,5.6,7.8,9]; % fake data
>> X = fix(V)==V;
>> V(X) % integer values
ans =
   1   4   9
>> V(~X) % values with decimal fraction
ans =
   2.3000   5.6000   7.8000

If you want to separate the value to the left and right of the decimal point, this works:

LD_RD = @(x) [fix(x)  rem(x,1)];                            % Separates Numbers Left & Right Of The Decimal

v = [1 2.1 pi 10 8.125]';
Result = [v LD_RD(v)]

Result =
            1            1            0
          2.1            2          0.1
       3.1416            3      0.14159
           10           10            0
        8.125            8        0.125

number=1.77;
integ=floor(number);
fract=number-integ;

@Dr. Siva Srinivas Kolukula: if you use fix then this also works for negative values:

>> N = -1.2;
>> I = fix(N)
I = -1
>> F = N-I
F = -0.20000
