The following compile-time error is uneecessary:
$ cat overflow.f90
program main
real :: a
a = exp(1000.)
print *,a
end program main
$ gfortran overflow.f90
In file overflow.f90:3
a = exp(1000.)
1
Error: Result of EXP overflows its kind at (1)
Assigning infinity would work just fine:
$ cat overflow2.f90
program main
real :: a
a = 1000.
a = exp(a)
print *,a
end program main
$ gfortran overflow2.f90
$ ./a.out
+Infinity
$ gfortran -v
Using built-in specs.
