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).
See section RealPart Intrinsic, for information on a GNU Fortran
intrinsic that extracts the real part of an arbitrary
COMPLEX value.
See section REAL() and AIMAG() of Complex, for more information.
