It depends:

  complex    C = ... -3 + 2i, 0, 1 + 3i ...                          
  composite      4, 6, 8, 9, 10, 12 ...
  integers   Z = ... -3, -2, -1, 0, 1, 2, 3 ...
  irrational F = ... \pi, \sqrt{2}, 0.121221222 ...
  natural    N = 1, 2, 3, 4 ...
  prime      P = 2, 3, 5, 7, 11, 13, 17 ...
  rational   Q = -\frac{1}{2}, 0.33333 ... \frac{5}{2}, \frac{11}{10} ... 
  real       R = ... -3, -1, 0, \frac{1}{5}, 1.1, \sqrt{2}, 2, 3, \pi ...
  whole      W = 0, 1, 2, 3, 4 ...
