Why engineers need both scientific and business calculators Message #1 Posted by Martin Pinckney on 18 Aug 2010, 11:05 p.m.
In addition to the obvious need for TVM and date calculations, I find the % functions on scientific calculators to be woefully lacking for the kind of % calculations that I do on a regular basis. Even the 27s (my overall favorite), which has excellent TVM and date math, only has the typical scientific implementation of % math. Of course I could easily write a Solver routine, but that takes precious memory.
This is one reason why I always keep a 17b handy.
Following the recent thread on the 30b, I was gratified to see it also has the full implementation of % math, what the 17 series calls "Business" functions (%Change, %MUcost, %MUprice, %Total). With the added bonus of the scientific functions, I can see why it has developed a big following.
