Hi, is there any special handling of NaN's or +/-INF's built into the VAL-procedure?
If so, where is it? ;) You ask why? Okay: I want to read in text files containing matrix data. The data is organized in rectangular manner, but some places are not valid because they are from physical measurements at places that are not reachable by any instrument. In this data files I have to use a convention to detect this invalid spots. My idea was to uses the string "NaN" or the like because anything else would narrow the range of input values (e.g. using -999 or similar for expressing the special case). If val could handle this itself, I'd not have to write any parsing code.
