The following table describes the types of the result.

Table 1. Types of the returned value and function argument
result	ARG1
`REAL(4)` vector	An `INTENT(IN)` `REAL(8)` vector
`REAL(8)` vector	An `INTENT(IN)` `REAL(4)` vector

Result Value

When ARG1 is a REAL(4) vector, each element of the result is equal to the corresponding element of ARG1, converted to REAL(8). The second and fourth elements of ARG1 are not used.

When ARG1 is a REAL(8) vector, the first and third elements of the result are equal to the corresponding elements of ARG1, converted to REAL(4). The values of the second and fourth elements of the result vector are undefined.
