On output, the value of the I/O list element is multiplied by 10**n
before transfer to the external record. Thus, a positive scale
factor moves the decimal point to the right; a negative scale
factor moves the decimal point to the left. Thus, the F field
descriptor alters the magnitude of the data.
E_field_descriptor
nPEw.d
On output, the basic real constant part of the I/O list element is
multiplied by 10**n, and "n" is subtracted from the exponent. For
a positive scale factor, "n" must be less than (d+2) or an output
conversion error occurs. Thus, a positive scale factor moves the
decimal point to the right and decreases the exponent; a negative
scale factor moves the decimal point to the left and increases the
exponent.
D_field_descriptor
nPDw.d
On output, the basic real constant part of the I/O list element is
multiplied by 10**n, and "n" is subtracted from the exponent. For
a positive scale factor, "n" must be less than (d+2) or an output
conversion error occurs. Thus, a positive scale factor moves the
decimal point to the right and decreases the exponent; a negative
scale factor moves the decimal point to the left and increases the
exponent.
G_field_descriptor
nPGw.d
On output, the effect for the G field descriptor is suspended if the magnitude of the data to be output is within the effective range of the descriptor (because the G field descriptor supplies its own scaling function). It functions as an E field descriptor if the magnitude of the data is outside its range. In this case, the scale factor has the same effect as for the E field descriptor.
