For input the same conditions apply as for F editing. For output the scale factor controls thedecimal normalization as in the D specifier.5.5.2.5 EN Format ControlThe EN specifier transfers real values using engineering notation.ENw.dENw.dEewhere w is the field width, d the number of digits in the fractional part and e the number of digitsto be printed in the exponent part.On output, the number is in engineering notation where the exponent is divisible by 3 and theabsolute value of the significand is 1000 > |significand | ≥1. This format is the same as the Eformat descriptor, except for restrictions on the size of the exponent and the significand.5.5.2.6 ES Format ControlThe ES specifier transfers real values in scientific notation. The ES format specifier has two basicforms:ESw.dESw.dEewhere w is the field width, d the number of digits in the fractional part and e the number of digitsto be printed in the exponent part.For output, the scale factor controls the decimal normalization as in the D specifier.On output, the number is presented in scientific notation, where the absolute value of thesignificand is 10> | significand | ≥ 1.5.5.2.7 F Format Control - Real Single Precision DataThe F specifier transfers real values. The form of the F specifier is:Fw.dwhere w is the field width and d is the number of digits in the fractional part.On input, if the field does not contain a decimal digit or an exponent, right-hand d digits, withleading zeros, are interpreted as being the fractional part.On output, a leading zero is only produced to the left of the decimal point if the value is less thanone.Fortran Intrinsics 161
