This doesn’t quite work. Assuming the program does a perfect job of rounding (something not guaranteed by the Fortran Standard), no such look-at-ASCII-strings test works, as I have written extensively elsewhere. See NOTE below. What is really is needed is to measure the relative error: how big is the difference when compared to the original numbers – something like ABS( B-A)/(0.5*A + 0.5*B) < TOLERANCE (or various other relative-error formulations like those found in DBLERR from ioapi/chkfi…
