I think it's still wrong: It is not possible for any value to fit into a field
of width w, but not into w+1.
Either
1) For the special case of a zero, we consider the minus sign and the decimal
symbol optional (which I think does not conform to the standard), then the
result should be:
print "(F3.0)", -0.0 ! => -0.
print "(F2.0)", -0.0 ! => -0 (or 0. or 0)
print "(F1.0)", -0.0 ! => 0
print "(F3.1)", -0.0 ! => -.0
print "(F2.1)", -0.0 ! => -0 (or .0 or 0)
print "(F1.1)", -0.0 ! => 0
or
2) We never consider the minus sign nor the decimal symbol optional (which I
think is required by the standard), then the result should be:
print "(F0.0)", -0.0 ! => -0.
print "(F3.0)", -0.0 ! => -0.
print "(F2.0)", -0.0 ! => **
print "(F1.0)", -0.0 ! => *
print "(F0.1)", -0.0 ! => -.0
print "(F3.1)", -0.0 ! => -.0
print "(F2.1)", -0.0 ! => **
print "(F1.1)", -0.0 ! => *
