I want to sort the positive integer values from a given values of real, rational, negative values in an array.

I want to sort the positive integer values from a given values of real, rational, negative values in an array. Suppose, I have a=[0.2, 0.78, -3, 10, 0.8, -6, 2, -5, 3, 0.6, 8 ] then answer should be a= 10, 2, 3, 8.

Answer 1

[Adam]

tol = 1e-5;
a = a( a > 0 & abs( floor(a) - a ) < tol  );

should work I think. Certainly it works on your example vector

Answer 2

[Andrei Bobrov]

out = a(a > 0 & rem(a,1)==0)

Answer 3

[KSSV]

a(a>1)
