HP-12C Platinum Emulator and Vertical Mode - Printable Version +- HP Forums (https://www.hpmuseum.org/forum) +-- Forum: HP Calculators (and very old HP Computers) (/forum-3.html) +--- Forum: General Forum (/forum-4.html) +--- Thread: HP-12C Platinum Emulator and Vertical Mode (/thread-14835.html) HP-12C Platinum Emulator and Vertical Mode - Gamo - 04-12-2020 06:26 AM HP provided the Emulator for HP-12C, HP-12C Platinum and HP-15C These emulator when view in vertical orientation mode you will get a basic calculator and only the exception is the HP-12C Platinum where you get the "Tip Calculator" function. Others doesn't have even the percent key in verticle mode. I noticed that to calculate percent is an easy task. For example: 100 + 10% = 110 and the percent amount is 10 Keystroks steps are 100 [ENTER] [ENTER] .1 [x] display 10 [+] display 110 ------------------------------------------------- Since HP-12C Platinum got the Tip Calculator function this can be use for adding tax or discount percent problem same as using the Percent function. For example: RPN mode 100 + 10% = 110 and the percent amount is 10 Keystroks steps: Default input at Split key: 1 g [Split] 100 g [Bill] display 100.00 10 g [Tip%] display 10.00 g [Tip] display answer 10.00 g [Total] display answer 110.00 If you need to calculate discount percent using above example [RCL] g [Bill] display 100.00 [RCL] g [Tip] display 10.00 [-] display answer 90.00 --------------------------------------------------- Remark: Since 1 is input to [Split] as default any other input and output can be use to calculate percent addition and percent subtraction problems. This will be a very handy calculator app in vertical mode when you need to use only one hand on the go calculations. [RCL] g [Bill] [RCL] g [Tip%] [RCL] g [Split] [RCL] g [Tip] [RCL] g [Total] Five variables above can be use as a Store Registers --------------------------------------------------- Gamo RE: HP-12C Platinum Emulator and Vertical Mode - Massimo Gnerucci - 04-12-2020 10:29 AM Do you really need a program to calculate a tip or a percentage? I am astonished.

This is not a program but a function feature that included on HP-12C Platinum. It is good to have at hand to quickly calculate percent problem. Gamo
