Intel® Fortran Compiler 16.0 User and Reference Guide
If w (the field width) is omitted for the data edit descriptors, the system applies default values. For the real data edit descriptors, the system also applies default values for d (the number of characters to the right of the decimal point), and e (the number of characters in the exponent).
These defaults are based on the data type of the I/O list item, and are listed in the following table:
|
