Does anyone have a function or know where I could get one that will convert a double (or at least a float) to a character string? It looks like a hard problem to me, one that would take quite a while to write, and I might never get it working. If the double was fairly small (say 8 or 10 digits or so) the character string should just contain all the digits and decimal point, but if it was very huge (or very tiny) the string should contain the e+ or e- representation. I'd really appreciate any help on this. Thanks very much. Jeff Hartkopf Internet: hartkopf@tramp.Colorado.EDU

Of course, the formate argument of this function should be different for varibles with differrent size of values according to your requests. So you would have to take conditional test on the values of the varibles before you call sprintf() with desired formate. -ping
