Real Intrinsic
..............
Real(A)
Real: `REAL' function. The exact type is `REAL(KIND=1)' when argument
A is any type other than `COMPLEX', or when it is `COMPLEX(KIND=1)'.
When A is any `COMPLEX' type other than `COMPLEX(KIND=1)', this
intrinsic is valid only when used as the argument to `REAL()', as
explained below.
A: `INTEGER', `REAL', or `COMPLEX'; scalar; INTENT(IN).
Intrinsic groups: (standard FORTRAN 77).
Description:
Converts A to `REAL(KIND=1)'.
Use of `REAL()' with a `COMPLEX' argument (other than
`COMPLEX(KIND=1)') is restricted to the following case:
REAL(REAL(A))
This expression converts the real part of A to `REAL(KIND=1)'.
Note:RealPart Intrinsic, for information on a GNU Fortran
intrinsic that extracts the real part of an arbitrary `COMPLEX' value.
