calculations in general
I am new to this board; you guys are a total benefit to your fellow surveyors.
Maybe someone can offer some insight here:I have been paying a programmer to restore an old Husky FS3 and also upgrade it with his own software that enhances or supports the original Tripod Data Systems program.
He seems to think that it is important that survey calculations be based on 18 significant digits rather than 12 significant digits. His trying to solve or program for this has been causing him difficulty and delay in getting the program completed.
Does anyone know if it is important to be able to do calcs based on using 18 vs. 12 significant digits?
I may be over-simplifying this, but all I know is that in the end result, when we manually enter a coordinate value into a handheld, we seldom enter it beyond 3 or 4 decimal places. And the same goes for transferring data back and forth, most people choose 3 or 4 decimal places when configuring the transfer.
Is number crunching based on significant digits an entirely different concept that what I am describing above relating to decimal places ??
