print *, 2+3, 2-3, 2*3, 2/3, 2/3.0, 2.0/3, 2**3
end

Output1

           5          -1           6           0  0.666666687      0.666666687               8

2/3 = 0 in Fortran because the quotient of two integers is truncated to an integer. The quotient of an integer and a real is a real.

print*,2+3,2-3,2*3,2/3,2/3.0,2.0/3,2**3

gives

5 -1 6 0 0.6666667 0.6666667 8

2/3 = 0 in Fortran because the quotient of two integers is truncated to an integer. The quotient of an integer and a real is a real.
