List-directed output editing of REAL values will minimize the number of digits that are emitted by calculating a decimal value that, if read back in to a REAL variable of the same kind, would compare equal. This behavior is causing some confusion when applied to list-directed output of large REAL(2) values. Specifically, the value HUGE(0._2) (which is 0x7bff in hex) is exactly 65504, but is edited to 65500. by list-directed output, which selects F0 editing, minimizes the value to 6.55e4, and then formats it without the exponent. This small patch changes that behavior for cases where the output of digit-minimized F editing has no digits after the decimal point and zeroes need to be emitted before it due to the decimal exponent. Digit minimization is disabled in this case and the exact digits are emitted instead.
