Intel® Fortran Compiler 16.0 User and Reference Guide
Real and complex editing is controlled by the F, E, D, EN, ES, and G data edit descriptors.
If no field width (w) is specified for a real data edit descriptor, the system supplies default values.
Real data edit descriptors can be affected by specified scale factors.
Do not use the real data edit descriptors when attempting to parse textual input. These descriptors accept some forms that are purely textual as valid numeric input values. For example, input values T and F are treated as values -1.0 and 0.0, respectively, for .TRUE. and .FALSE.
