DPROD — Double product functionDPROD(X,Y) returns the product X*Y.
Fortran 77 and later
Elemental function
RESULT = DPROD(X, Y)
| X | The type shall be REAL. |
| Y | The type shall be REAL. |
The return value is of type REAL(8).
program test_dprod
real :: x = 5.2
real :: y = 2.3
real(8) :: d
d = dprod(x,y)
print *, d
end program test_dprod
